Version 6.15 July 06, 2015
1. New: When split-half resampling was enabled,
the incorrect permutation test was called for the
overall assessment of significance. This has been
fixed. This bug does not affect permutation tests
done without split-half resampling.
Version 6.14 December 9, 2014
1. New: Fixed bug in using the wrong mean-centering
approach for confidence interval estimate for
non-rotated PLS scores.
Version 6.1311050 November 5, 2013
1. New: computation change for "Single Condition Task
PLS". Therefore, please run such analysis again with
this latest version of PLS applications.
2. Fix: crash when you have more numbers of bootstrap
than what is limited by numbers of subject.
Version 6.1306040 June 4, 2013
1. New: add "Use segment data" checkbox under Structural
PLS analysis window. By default, it is selected (i.e.
assuming that you are using segment data). If you are
not using segment data, you should deselect it.
2. New: change label by replace ucorr_prob & vcorr_prob
with p_braincorr & p_designcorr.
Version 6.1305080 May 8, 2013
1. New: plscmd_cluster_report.m is provided to get
cluster information for command line PLS application
(i.e. pls_analysis.m under plscmd folder). The result
is not viewable by GUI application. If you have PLS
result file from GUI application (i.e. *result.mat),
you should use GUI, or create_cluster_report.m to
create cluster report, which can be viewed under GUI,
or view_cluster_report.m.
Version 6.1305010 May 1, 2013
1. Fix: missing menus are added for multiblock PLS.
Version 6.1304190 April 19, 2013
1. New: ucorr_prob and vcorr_probs from splithalf test
are displayed in "Design LV and Design scores Plot".
2. New: bootstrap type feature is temporarily disabled.
3. Fix: bug crashs single subject result.
4. New: User Guide for PLS Applications is modified.
http://research.baycrest.org/pls/UserGuide.htm
Version 6.1304020 April 2, 2013
1. Fix: bug in single condition Mean-Centering PLS.
Version 6.1303150 March 15, 2013
1. Fix: bug in 'session2sessiondata' when run it from
different folder.
Version 6.1303010 March 1, 2013
1. New: An upgrade of PLS applications has been done on
29-OCT-2012. For certain reasons, we did not release
that new version until now. Therefore, I would like
to repeat some of the whatsnew contents that have
been listed under Version 6.1210291 below.
2. New: Since PLS user interface will use Command-Line
PLS to run all PLS analysis, folder plsgui and plscmd
must be kept under the same parent folder, and their
folder names (i.e. plsgui and plscmd) can not be
changed.
3. New: session.mat / datamat.mat files are now combined
to a single sessiondata.mat file. To provide seamless
upgrade, a new program "session2sessiondata.m" is
included. You can run this program to convert old
session / datamat files to new sessiondata file,
either for a single session or for entire folder. For
more information, please type:
help session2sessiondata
4. New: Command-Line PLS will take optional argument for
other parameters like num_permutation etc. For more
detail, please type:
help pls_analysis
Version 6.1302280 February 28, 2013
1. New: When some conditions of behavior measures are
not available in behavior block of Multiblock PLS, the
brain data of those unavailable conditions will be
included in permutation loop.
2. New: "nonstrat" boot type is purely experimental,
do not select it unless you have good reason.
Version 6.1302200 February 20, 2013
1. New: Brain data, not behavior data, is resampled for
splithalf permutation.
2. New: Non-Rotated PLS is changed back to old way (i.e.
to use un-normalized salience) for conventional
bootstrap in order to avoid bootstrap ratio scaling
problem.
Version 6.1301160 January 16, 2013
1. Fix: Result window for correlation plot crash problem
for certain skewed data.
Version 6.1301040 January 4, 2013
1. New: The electrode channel layout of MEG CTF-150 is
modified.
Version 6.1212310 December 31, 2012
1. New: "non-rotated bootstrap" and "splithalf
permutation" is linked, and "non-rotated bootstrap"
selection is removed.
Version 6.1212060 December 6, 2012
1. New: If Number of Permutation Split is greater than
0, ucorr_prob_LV & vcorr_prob_LV will be displayed in
Permuted Singlar Values window.
2. Fix: A bug in new code (never published) to generate
bootstrap sample for method 3 & 5.
Version 6.1211270 November 27, 2012
1. Fix: Possible inverse zoom problem after Matlab 7.4.
Version 6.1211200 November 20, 2012
1. New: Removed unused fields compare_v, v_se, and
zero_v_se from boot_result.
Version 6.1211140 November 14, 2012
1. Fix: Within "parfor-loop", the figure command does
not work properly. So I have to use command window
display, rather than progress bar figure, to show
the steps of splithalf permutation.
Version 6.1211130 November 13, 2012
1. Fix: Checked and made sure location inputs for text()
command are in double; otherwise MATLAB may crash.
Version 6.1211120 November 12, 2012
1. New: If there are session / datamat files in current
folder, but there is no sessiondata file, it indicates
that this is probably an old PLS user, who is not aware
that the session / datamat files need to be combined to
sessiondata file. New plsgui & batch_plsgui will show
prompt message, if this user is trying to run analysis
or edit session profile.
2. New: After PLS detects the availability of parallel
setting, now it will further detects whether matlabpool
is open. Only when matlabpool is open (i.e. the size
of pool is greater than 0), the "parfor-loop" will be
selected in splithalf permutation block. Otherwise,
regular "for-loop" will always be selected.
Version 6.1211010 November 1, 2012
1. New: Program "session2sessiondata.m" can be applied
on both old session filename or session folder. For
example: session2sessiondata('.') will convert all
the old session / datamat files in the current folder
to new sessiondata files. Note: old session / datamat
files will NOT be removed or modified.
2. Fix: Bug in splithalf_perm_par function.
Version 6.1210290 October 29, 2012
1. New: Since PLSgui will use Command-Line PLS to run
all PLS analysis computations, folder plsgui and
folder plscmd must be kept under the same parent
folder.
2. New: session.mat / datamat.mat files are now combined
to a single sessiondata.mat file. To provide seamless
upgrade, a new program "session2sessiondata.m" is
included in PLSgui. You can run this program to
convert old session / datamat to new sessiondata. For
more information, please type help session2sessiondata
3. New: Command-Line PLS will take optional argument for
other parameters like num_permutation etc. Please type
help pls_analysis for more detail.
4. New: Natasa's features are included, which includes:
splithalf permutation, nonstrat bootstrap, non-rotated
bootstrap, non-rotated multiblock PLS, parallel option,
mean-centering type, correlation mode.
5. New: Command-Line cluster report programs are available
to create and view cluster report for both old and new
version of PLSgui result file.
Version 5.1209101 September 10, 2012
1. New: Will check percentage of brain region in image
volume before creating Structural datamat. If the
mask is larger than 25% of the volume, the program
will ask user whether to proceed or to stop and check
brain mask file.
Version 5.1206281 June 28, 2012
1. Fix: Disabled false alarm about 64-bit single precision
between MATLAB version 7.10 and 7.39.
Version 5.1110251 October 25, 2011
1. Fix: Structural label feature is now available even
there is no bootstrap test in result file.
Version 5.1110202 October 20, 2011
1. New: If the dimension of raw imaging data is 41x48x35,
"View 41x48x35 Structural Label" menu is added under
"View" menu for fMRI result window; otherwise, if the
dimension of raw imaging data is not 41x48x35, you
won't see this menu. When this menu is checked, the
label of structural map will be displayed on top of
BLV or BSR area.
Version 5.1109191 September 19, 2011
1. New: Duration lenth can be entered for "Use HRF" feature
under "Blocked fMRI" session window. By default, it is
set to 0, which is for event-related response. For
epoch-related response, you need to set the duration.
2. New: In Generate Datamat window, now we have HRF1 and
HRF2. In HRF1, TR will be further divided into smaller
bin when calculating design matrix, and the default HRF
is SPM HRF. In HRF2, TR is always the smallest unit when
calculating design matrix, and the default HRF is GAMMA
function from AFNI's HRF.
3. New: "Degree of Legendre Polynomials for regressors"
field is added. By default, it is 0, which provides a
single column of all ones. This is also a feature from
AFNI's HRF.
4. PLS User Guide is also updated:
http://www.rotman-baycrest.on.ca/pls/UserGuide.htm
Version 5.1105181 May 18, 2011
1. Fix: Write permission will be checked before starting
PLS analysis.
Version 5.1105121 May 12, 2011
1. Add in FAQ: When "Use HRF" is selected, the order of
slice must be sequential and ascending if you are
trying to use decimal number in "onsets" field.
2. Add in FAQ: Get some value from "*result.mat" in MATLAB
command window.
Version 5.1105052 May 5, 2011
1. Fix: "Run Info" window crash.
2. Fix: "HRF over run" window cannot bring to the front.
3. Fix: "HRF over run" window display error for skipped scan.
4. Fix: Message of "out of bound" scans for HRF fMRI.
Version 5.1105021 May 2, 2011
1. "Use HRF" selection box is available in Blocked fMRI
session profile window. This feature is actually
designed for Event Related fMRI. Since most of the
user interfaces are compatible with Blocked fMRI, I
have to build it on Blocked fMRI platform.
2. By default, SPM's HRF model is used. However, you can
also design your own HRF model by clicking "Customize
HRF" button. You can either type 1-D vector in the
"Data:" field, or write your 1-D vector (all numbers)
in a text file and then load this text file. You can
also plot the convolved HRF by clicking
"Plot Regressors" button.
3. When you use HRF feature, there is no more necessary
to do "Normalize data with ref. scans", since the low
frequency drift is removed by SPM High Pass filter.
There is a selection box called "Use SPM ReML" in
"Create Datamat" window. If this box is selected (by
default), the voxel outlier over the run will also
be removed.
4. While developing the "Use HRF" feature, I noticed some
buggy functions, and they have been taken cared in the
following manner: "Number of scans to be skipped" field
is moved to the "Edit Runs" window. "Run to be included"
field is removed. If you want to exclude the run, simply
open "Edit Runs" window, go to the run that you need to
delete, and click Edit->Delete. "Slice to be ignored"
field is also removed. We can pre-process the raw image
to remove those slices.
Version 5.1102241 February 24, 2011
1. Use 'round' instead of 'floor' to round the decimal
in fMRI onset time.
Version 5.1102041 February 4, 2011
1. Fixed a bug when loading a quaternion form NIfTI data.
Version 5.1102011 February 1, 2011
1. Fixed bugs in "Task PLS Brain Scores with CI" window
for Multiblock PLS. The analysis will need to be
re-run in order to see the fix.
2. Added a function (dset2img.m) to create a simulated
4D NIfTI image and a corresponding brain region mask
from a SUMA's 1D.dset file in order to run PLS.
3. Added a function (plsgui2dset.m) to extract BrainLV
/ BSRatio from PLS result to SUMA's 1D.dset files
in order to visualize the BrainLV result and BSRatio
result from SUMA.
4. Added a function (fmri2dset.m) to extract fMRI datamat
to a SUMA's 1D.dset file for special SUMA processing.
5. Added a function (dset2fmri.m) to update fMRI datamat
with the SUMA processed 1D.dset file.
Version 5.1007191 July 19, 2010
1. Added "Load from Batch" button in PLS analysis window.
Version 5.1004262 April 26, 2010
1. Added "Subject Amplitude for Given Timepoints" item
under "View" menu of ERP salience plot. This item
will bring a "Plot Detail" like window, which allows
you to plot the response of datamat value, and extract
multiple time points of the datamat value.
Version 5.1003291 March 29, 2010
1. Reversed the feature of checking timestamp in the
result file. Because it brings too many troubles,
the program will no longer warn you if you forget
to re-run the PLS after modifying the datamat. It
will be users' responsibility to re-run the PLS
whenever a datamat is changed.
Version 5.1003081 March 8, 2010
1. Added options for normalizing volume mean when using
batch file to create datamat.
Version 5.1002191 February 19, 2010
1. Fixed a bug of false alarm for duplicated bootstrap
order.
Version 5.0912111 December 11, 2009
1. Fixed a bug when reading a volume from 4D Analyze data.
Version 5.0912081 December 8, 2009
1. Add data check when using batch to create datamat.
Version 5.0912072 December 7, 2009
1. Since MATLAB allows less amount of data to be saved
by using '-append' switch than without using '-append'
switch, '-append' switch has been take away when saving
result files. However, the saving time will be a longer.
So, the "Save GUI Position" & "Save Display Setting"
under "Tools" menu of the first window is also taken
away.
2. Fixed a scroll bar bug.
Version 5.0912011 December 1, 2009
1. Fixed a bug for Brain Score Plot crash when some
subjects are deselected in Structural PLS.
Version 5.0910261 October 26, 2009
1. Thanks to the feedback from Yunjo, and the recursion
limits is set to 100 for cluster report creating. On
telesto computer that I tested today, RecursionLimit
is set to 100 by default for all MATLAB versions
lower than MATLAB 7.6 (R2008a), and it is set to 500
by default for MATLAB 7.6 & 7.8. However, with higher
recursion limits, 2 or more different clusters are
combined together unnecessary. This problem is solved
when RecursionLimit is set to 100 just for PLS.
Version 5.0910111 October 11, 2009
1. Fixed a bug in MRI behavior & multiblock PLS.
Version 5.0910022 October 2, 2009
1. Value of confidence level that is input by users
for bootstrap test is now saved in result file
under boot_result.Clim.
2. Fixed several bugs that cause crash when displaying
result file.
Version 5.0909171 September 17, 2009
1. Single subject analysis with different number of
onsets among conditions can also be analyzed.
Version 5.0908261 August 26, 2009
1. Added "Task PLS Brain Scores with CI" feature for
Multiblock PLS analysis and its result window.
Like the one in Mean-Centering & Non-Rotate PLS,
you must run bootstrap test in order to get this
feature.
Version 5.0908231 August 23, 2009
1. Fixed a progress bar bug, which cause crash.
Version 5.0908141 August 14, 2009
1. Fixed a bug in using "RandStream" function, which
cause crash.
Version 5.0908041 August 4, 2009
1. Fixed a bug in selecting Cluster Report Options,
which does not allow any selection in some cases.
Version 5.0907231 July 23, 2009
1. Using "RandStream" instead of "rand('state')" to
control the state of MATLAB random functions in
MATLAB 7.8 (R2009a) and above.
Version 5.0907221 July 22, 2009
1. Voxel with NAN value will be marked as non-brain
area.
Version 5.0907171 July 17, 2009
1. Fixed ERP plot detail window crash problem for
new version of MATLAB.
Version 5.0907162 July 16, 2009
1. Added file format field in ERP session window, so
some data like ANT, NeuroScan, can be properly
extracted.
Version 5.0907141 July 14, 2009
1. Fixed a bug to select a file name in subject select
window.
Version 5.0907131 July 13, 2009
1. If you are using MATLAB 7.4 (R2007a) and above, the
warning message for MATLAB Bug Report ID 268001
regarding to the single precision computation on
64-bit Intel based system is now removed.
Version 5.0906092 June 9, 2009
1. Program "flip_plsgui.m" is created and only served
as a remedy for those who missed orientation check
during datamat creation. Before a datamat is created,
please always remember to use the existing "Check
Image Orientation" button in "Create Datamat" window
of "plsgui" program to do the flipping. If you are
using "batch_plsgui" program, you can flip raw images
using "flip_lr.m" program. This program is in the same
folder as "batch_plsgui" and "plsgui" program. By the
way, "flip_lr.m" will save image in NIfTI format.
Version 5.0905112 May 11, 2009
1. Added a new feature under "Tool" menu of ERP display
window to export the plotted wave data and the time
information inside the window that is clicked.
2. Fixed a bug in displaying Condition Average and
Condition Difference for ERP module.
Version 5.0904241 April 24, 2009
1. For Task PLS bootstrap test, variable 'b_scores2'
(or 'brainscores2') is saved under 'boot_result'
structure. This Brain Score 2 here is created with
mean-centered datamat, which is used in the "Task
PLS Brain (or Scalp) Scores with CI" feature.
2. Command line program "batch_alter_fmri_onset.m" is
created to alter the onset values in type one batch
script for creating fMRI session/datamat files.
Version 5.0903041 March 4, 2009
1. When you display result file, missing datamat or
session file will now be prompted.
Version 5.0902131 February 13, 2009
1. Data exported from Voxel Intensity Plot window now
contains 'data_mean' variable, which stands for the
the mean values numbers that are displayed in the
Voxel Intensity Plot window.
Version 5.0901211 January 21, 2009
1. Fixed a bug in "Datamat Correlations Plot" window
to display result without bootstrap.
Version 5.0901071 January 7, 2009
1. Add "Multiple Corrs Extraction" in PET Behavior
result window to extract multiple correlation
values.
Version 5.0811121 November 12, 2008
1. Fixed the problem of "Datamat Correlations Plot"
crash on new version of MATLAB.
2. Fixed "Datamat Correlations Response" data export
error for PET & Structural modules when 2 groups
of datamat have different masks.
Version 5.0810231 October 23, 2008
1. Fixed problem to list a single file in old MATLAB.
Version 5.0809051 September 5, 2008
1. Keyword "intel_system" can be added into PLS analysis
batch text file. By default, it is set to 1. If you
are sure that you are using 64-bit non-Intel system
with Matlab 7 and above, you can set it to 0 to allow
single precision math computation.
Version 5.0808261 August 26, 2008
1. Fixed a bug when condition(s) are removed from MRI
session file. Those modified session file will make
PLS analysis crash. In that case, you can apply a
patch to those session file before re-run analysis.
Here is an example of how to apply the patch:
mri_session_patch('a_BfMRIsession.mat');
or mri_session_patch('b_fMRIsession.mat');
2. Absolute value is used for elements inside function
of square root to prevent complex number.
3. When clicking "Save Current Display" in File menu of
the result display window, the colormap is now saved
to a MATLAB file that is ended with "_cmap.mat".
4. "reslice_nii.m" is provided to preprocess the NIfTI
format image file that containing non-orthogonal or
oblique affine transform.
Version 5.0807231 July 23, 2008
1. Changed "Reference Scan Onset" label under MRI "Edit
Condition" window to "Relative Ref. Scan Onset" to
prevent users from using absolute scan onset.
2. Updated PLS User Guide with the changes.
Version 5.0807161 July 16, 2008
1. Added "Single reference scan" feature in creating
MRI datamat window.
2. Added "Peak threshold" feature in Cluster report
options window.
Version 5.0807091 July 9, 2008
1. Modified both computation and display routine of the
"Brain (or Scalp) Scores Plot for Task PLS" feature,
and renamed it to "Task PLS Brain (or Scalp) Scores
with CI". The menu item only available for Mean-
Centering PLS and Non-Rotated Task PLS with more
than one bootstrap tests.
2. Since the computation is changed, you will be prompted
to re-run PLS with this modified program.
Version 5.0806111 June 11, 2008
1. Fixed a bug in non-rotated PLS.
Version 5.0806031 June 3, 2008
1. Added Non-Rotated Behav PLS analysis feature for all the
modules of PLSgui and PLScmd.
2. Added "Brain (or Scalp) Scores Plot for Task PLS" for all
the modules of PLSgui. If there are Bootstrap test loops,
the distribution of usc (Brain or Scalp Scores) are also
computed for both PLSgui and PLScmd.
3. Like other modules in PLSgui, now ERP module also splits
its Threshold field in BootStrap Option wildow into two
field - Pos.Thresh and Neg.Thresh.
4. Removed "Using Helmert Matrix" menu selection from the
contrast window.
5. Created last good files folder that can be accessed from:
http://www.rotman-baycrest.on.ca/pls/source/lastgood
or /b/jimmy/plsgui/lastgood & /b/jimmy/plscmd/lastgood
on Rotman cluster servers.
Version 5.0804282 April 28, 2008
1. More changes in generating cluster report. First, undo
the change I did on April 25, 2008. Actually, there is
no skipped clusters. According to the comments of the
original author of this cluster report program, when a
cluster found later can be joined to the cluster found
earlier, they should be combined together. According to
the comments, the reason that the program can not find
all active voxels in the earlier cluster at once is due
to the recursion limit of MATLAB. Second, there is a
bug in the original cluster report program, which lost
some found active voxels in the clusters (because of
the combination). Now this problem has been fixed. I
still have to let you know that due to the recursion
limit, you may not be able to find all active voxels
in a cluster, or one cluster is divided to several
clusters, etc. I have updated PLS User's Guide and
FAQ, which will provide you more details.
Version 5.0804251 April 25, 2008
1. Fixed a bug in generating cluster report, which skipped
some clusters.
Version 5.0803181 March 18, 2008
1. Cluster with minimum cluster size in "Set Cluster
Report Options" window is included. i.e. If "Minimum
cluster size" is equal to 5, a cluster with 5 voxels
is now counted.
Version 5.0802271 February 27, 2008
1. Fixed a bug that causes crash when changing to other
view from Axial view in fMRI Bootstrap Ratio window.
Version 5.0802221 February 22, 2008
1. Implemented the workaround for "persistent" variable
that is provided by Matlab Tech Support, which can
prevent from using global variable as a replacement
for MATLAB 7.2.
Version 5.0802011 February 1, 2008
1. Instead of throwing an error for a very oblique image,
now only a warning message will be displayed.
Version 5.0801211 January 21, 2008
1. When the "Filter" of simplified UIGETFILE/UIPUTFILE
is not using wildcard (* or ?), its "File Name"
field is now filled.
Version 5.0801031 January 3, 2008
1. Added "EGI128_v2" electrode system for ERP module.
Version 5.0712061 December 6, 2007
1. Last change for creating MRI datamat with onset
marked -1 still having problem with certain data.
It is now fixed.
Version 5.0711221 November 22, 2007
1. Modified simplified version of UIGETFILE/UIPUTFILE
so it will now take directory name from the input
filter pattern and the File Name field.
Version 5.0711211 November 21, 2007
1. Filter in simplified version of UIGETFILE/UIPUTFILE
is now working on new version of MATLAB.
Version 5.0711203 November 20, 2007
1. Fixed a problem to load datamat file for analysis
in the simplified version of UIGETFILE/UIPUTFILE
window.
2. Made simplified version of UIGETFILE/UIPUTFILE work
on directory and filter.
Version 5.0711161 November 16, 2007
1. Modified Threshold field on the Result display
window of PET, Structure & MRI module. Now two
different thresholds (Pos / Neg Thresh) are set
up, and it is only for the situation where the
distribution of data is extremely biased.
Therefore, it is still suggested to use symmetric
threshold, and it is not recommended to modify the
threshold arbitrarily, unless you know what you are
doing.
Version 5.0711132 November 13, 2007
1. Fixed a bug when displaying Structural PLS data in a
different path.
Version 5.0711121 November 12, 2007
1. Fixed the bug when creating MRI datamat with certain
onset marked -1. For those existing (already created)
datamats, a patch needs to be applied before re-run
analysis. Here is an example of how to apply patch:
mri_datamat_patch('a_BfMRIdatamat.mat');
or mri_datamat_patch('b_fMRIdatamat.mat');
To create a new MRI datamat, you don't need patch.
Version 5.0711061 November 6, 2007
1. Fixed a bug in task PLS analysis with single subject
data.
Version 5.0711051 November 5, 2007
1. MATLAB changed their UIGETFILE & UIPUTFILE, which
causes some of the old scripts no longer to be able
to run on some platform with new version of MATLAB
(version 7 and above). Therefore, I have to built
a simplified vesion to workaround this issue.
Version 5.0710161 October 16, 2007
1. Fixed a bug when using Matlab Version 7.4.0 to
build Structural module session file.
Version 5.0710091 October 9, 2007
1. Bootstrap input dialog box in plscmd is replaced
by input text string as requested.
Version 5.0709121 September 12, 2007
1. Fixed a bug to create datamat for single slice
Structural MRI data.
Version 5.0705021 May 8, 2007
1. Command-line PLS help information is included in the
Appendix of PLS User's Guide.
Version 5.0705021 May 2, 2007
1. Modified "load_ant.m" based on the changed .avr file
information provided by ANT staff. So now PLS can
load ANT's average binary data format again. Please
see detail in:
http://www.rotman-baycrest.on.ca/pls/FAQ.txt
Version 5.0704241 April 24, 2007
1. A rounding issue in the code caused multiple voxel
extraction routine to fail in some situations. This
problem is fixed now.
Version 5.0704231 April 23, 2007
1. Stop supporting ANT average binary data format.
2. Start supporting users' own scalp electrode system.
3. Updated http://www.rotman-baycrest.on.ca/pls/FAQ.txt
and http://www.rotman-baycrest.on.ca/pls/UserGuide.htm
Version 5.0704201 April 20, 2007
1. Fixed the display of CTF150 location for ERP module.
2. Jordan Poppenk found that the voxel value can be
negative, if a brain mask is used. So the previous
restriction is remvoed from FAQ file.
3. "load_nii" will automatically load SPM affine matrix
M in .mat file, if it detects that the file name is
the same as the Analyze file.
Version 5.0704091 April 9, 2007
1. Modified normalize.m and add load_acq.m.
Version 5.0703272 March 27, 2007
1. Fixed a bug for the wrong scaling dispay in the
Subject and Average Amplitude window in the ERP
module, which was introduced from on March 9
from version 5.0703091.
Version 5.0703221 March 22, 2007
1. Fixed a bug in saving data to a text file.
Version 5.0703191 March 19, 2007
1. Fixed a bug in exporting cluster report all location.
Version 5.0703151 March 15, 2007
1. Fixed a bug in bootstrap test for Multiblock PLS.
Version 5.0703091 March 9, 2007
1. The display of "Design LV and Design Scores" window
in other module follows the way that is already in
place for E.R.fMRI. i.e. all the groups will display
together in the same window.
2. The subject name in all MRI module is now using the
datamat prefix name defined in its session file.
3. "Scale by Singular Value" button is added in all
result display window. It is the same button called
"Rescale" previously only for PET and Structural.
4. The "Voxel Intensity Response" window will get the
same axis for all the groups. However, if you first
click a new group that exceeds the min/max of currnet
value, the axis will still adjust to the new min/max.
If you click back, the axis will stay unchanged.
5. Added a "Create Batch File" button in the "Run PLS
Analysis" window. So people can using this created
plain text file (batch file) to feed "batch_plsgui"
program. We may also do some test with an external
program that is compiled in C language, and it will
also use the same batch text file to read MATLAB
files (Session / Datamat file) and write a MATLAB
file (Result file). but it is not available yet.
6. Updated PLS User's Guide.
Version 5.0703011 March 1, 2007
1. Prompt user to delete some subjects in Structural
session information window when there is too much
data to process.
Version 5.0702261 February 26, 2007
1. Mofified User's Guide.
2. Fixed false warning when there is no match subject files.
Version 5.0702221 February 22, 2007
1. Used different way to check low variability of behavior
data for bootstrap test.
Version 5.0702212 February 21, 2007
1. "num_LowVariability_behav_boots" field is added to the
"boot_result" struct for the bootstrap test containing
behavior data. In the case that behavior data does not
have enough variance the following warning message will
also be displayed in the command window: "For at least
one behavior measure, the minimum unique values of
resampled behavdata doesnot exceed 50% of its total".
2. Fixed display problem for the plot with special character
in subject name or condition name. The program now can
accept special character (e.g. underscore "_").
3. Removed "Merge Conditions" button for Structural PLS.
Version 5.0702161 February 16, 2007
1. Fixed a bug in bootstrap test in handling bad behavior
data.
2. MATLAB 7 has a little difference in handling "uiputfile"
in that it will include the wildcard string PLS program
provided. This problem has been solved.
3. Made a workaround for single condition Mean-Centering PLS.
4. Structural MRI module is implemented.
Version 5.0702061 February 6, 2007
1. Fixed a bug in permutation test of Non-Rotated PLS for
MRI modules.
2. Fixed a dialog box error message asking about default
button.
3. In datamat correlation window for behavior PLS result,
the "Save ... to IMG file" will now apply the bootstrap
mask that filters out the unreliable voxels.
Version 5.0701151 January 15, 2007
1. Fixed a bug in detecting group contrast rank deficiency.
Version 5.0701101 January 10, 2007
1. When exporting all locations of cluster report, values
(BrainLV or BSRatio) for the corresponding voxels are
also exported into "*_MODULEcluster_num.txt". The first
column of this file is still Cluster ID#; the second
column of this file is now the corresponding BrainLV
or BSRatio value; the last 3 columns are still XYZ
locations.
Version 5.0701032 January 3, 2007
1. Integrated single precision math operation feature of
MATLAB 7 (R14) above into the PET & MRI modules of the
program. If MATLAB is running on 64-bit system, a dialog
box will be popped out to ask user for the system's
processor. If the answer is "Don't know" or "Intel
processor", double precision will be used according to
MATLAB Bug Report ID 268001. (If you are using RRI Linux
cluster, "telesto" is the only 64-bit system that has
non-Intel processor, which supports single precision math
operation).
2. Removed unnecessary rounding (ceil) for the bootstrap
test of behavior PLS analysis, which caused inaccuracy
when number of bootstrap is small. "zero_brain_se" is
also added in "boot_result", which represents the index
of those brain_se with zero standard error.
Version 5.0612081 December 8, 2006
1. Neuroscan version 4.3 also has 32-bit acquisition
for its continuous data files. By default, it collects
16-bit integer data with the original SynAmp (SynAmp1).
With SynAmp2, it will collect 32-bit integer data.
According to Neuroscan tech support, "this file format
must be determined prior to reading the file, i.e. there
is no flag within the file itself to identify a file as
32-bit". In order to read 32-bit data format, optional
input "fileformat" of "load_neuroscan.m" function must
be specified to 'cnt32'. For example, you can load data
using: ns = load_neuroscan('myfile.cnt', 'cnt32'); Type
"help load_neuroscan" for the usage of "fileformat".
Because now the continuous data file can be very large,
you can specify cnt_start_time and cnt_end_time. Their
units are "second". For example, if you only want to
extract data from 0 second to 1.998 second, you can type:
ns = load_neuroscan('myfile.cnt', 'cnt', '', 0, 1.998);
The actual rounded start_time and end_time will be
displayed in ns.start_time and ns.end_time.
Version 5.0612051 December 5, 2006
1. Added "behavior_name" field for the "analysis batch
file" processing program. Demo "analysis batch file"
are: batch_pet_analysis.txt, batch_erp_analysis.txt,
batch_bfm_analysis.txt, and batch_fmri_analysis.txt.
Version 5.0611021 November 2, 2006
1. Fixed a bug when brain mask only contains 1 slice.
Version 5.0609251 September 25, 2006
1. Both EGI 128-Channel and EGI 256-Channel are provided
along with BESA and CTF-150.
2. Script "erp_single_folder" is included in PLS for
a special reason, and we do not recommand normal user
to use this script.
3. Added "mat_into_hdr.m" script to convert SPM ANALYZE
Reoriented image file into NIfTI format and integrate
its matlab file into its header file.
Version 5.0609151 September 15, 2006
1. We decided to use XYZmm, voxel location with unit
in millimeter, for the entries of Multiple Voxel
Extraction" voxel location text file. In earlier
version, we were using XYZ, absolute voxel location,
for the entries of voxel location file. In order
to convert your absolute voxel location file to
voxel location with unit in millimeter, we provided
a handy script called "xyz2xyzmm.m".
2. Both "Peak Locations" and "All Locations" that are
exported from "File" menu in "Cluster Report" window
are also changed to voxel location with unit in
millimeter. This way, people perform "Seed PLS" do not
have to to any extra conversion.
3. "Posthoc Data" button in "PLS Analysis" window is
now removed.
4. Since new BESA file can have more than 1 header lines,
ERP code is modified to accommodate this change. That
means, ERP module can load BESA file with no header,
or with any amount of headerlines, as well as binary
files like NeuroScan, ANT, or EGI.
Version 4.0609071 September 7, 2006
1. A bug was introduced during last change (Version
4.0608291), in which the neighborhood voxels were
not exported without averaging together. Since last
change only applied on MRI "Multiple Voxel Extraction",
only MRI module was affected. It is now fixed.
2. In Matlab 2006a, the bootstrap test sometimes giving
you a feeling of "frozen". This is caused by the
bootstrap progress bar sometimes conflict with the
permutation progress bar. I have also fixed this.
Version 4.0608291 August 29, 2006
1. Modified "Multiple Voxel Extraction" part of the
program for MRI module, so it will consume less
memory. The result remains the same as the earlier
version.
Version 4.0608111 August 11, 2006
1. The message of "Duplicate bootstrap order" was not
popped out, and it is now fixed.
Version 4.0608091 August 9, 2006
1. When exporting all locations of cluster report, a new
file that is named "*_MODULEcluster_num.txt" will be
created at the same time as "*_MODULEcluster_all.txt"
file. In this new file, a column with cluster # is added
in front of XYZ locations to indicate which cluster each
exported voxel belongs to.
Version 4.0608021 August 2, 2006
1. Provided a workaround for "persistent" variable issue
in Matlab R2006a (a Matlab bug).
Version 4.0607111 July 11, 2006
1. Fixed a bug when moving existing session file while the
sub-folders also needs to be changed.
Version 4.0606231 June 23, 2006
1. "expand_nii_scan.m" is modified so the expanded image
volume scan files will be appended with a 4-digit
number starting from 0000.
Version 4.0606201 June 20, 2006
1. The original display routine assumed the result data
have both positive and negative values, and it crashed
otherwise. Now the problem is fixed, and it can display
all positive (or all negative) data.
Version 4.0606091 June 9, 2006
1. Cluster sizes were over counted during combination. It
is fixed now.
Version 4.0606061 June 6, 2006
1. Program "m2hdr.m" is created to integrate affine matrix
generated from old SPM into NIfTI *.hdr file.
2. There was a bug in converting some permuted images to
RAS orientation. It has been fixed now.
Version 4.0606011 June 1, 2006
1. There is a bug (crash) in fMRI non-rotate, if just
doing bootstrap test. It is fixed.
Version 4.0605261 May 26, 2006
1. Modified cluster report "Export All Location" menu,
and now the voxel is in the order of clusters. If you
have two clusters, one with 30 voxels, and the other
one with 20 voxels, the first 30 lines correspond to
cluster one and the second one correspond to cluster
two. If you have saved "*cluster.mat" from previous
version, you have to re-generate it before exporting
all locations.
Version 4.0605111 May 11, 2006
1. When clicking "Save Current Display to IMG file", or
"Save BLV/BSR result to IMG file" under "File" menu,
those img/hdr files can be saved in a directory that
is different from result file directory.
Version 4.0604261 April 26, 2006
1. When editing existing fMRI session file, existing
conditions were protected to prevent being modified.
Now, the protection is removed.
Version 4.0604201 April 20, 2006
1. Size of some image data is incorrectly larger than
what specified in "hdr.dime.dim" field. So it caused
problem to load image data. Image data is now always
loaded according to the size that is specified in
its header.
2. When editing existing fMRI session file, the "DELETE"
buttons in "Edit Condition" window is now enabled.
Version 4.0603211 March 21, 2006
1. Tools for NIFTI image now supports both COMPLEX64 and
COMPLEX128 data type.
Version 4.0603192 March 19, 2006
1. "UserGuide.htm" file is included in the package to
replace the old out-of-dated "*_hlp.txt" files. The
entire PLS User's Guide is still under processing.
Version 4.0603062 March 6, 2006
1. Modified "Export Data" for fMRI "Response Function Plot"
and "Temporal Brain Scores Plot". The "st_evt_list" in
the exported file is always sorted as condition-within-
subjects, so as the "data" variable.
2. Added "data_mean" variable to the above exported MATLAB
data file. Rows of "data_mean" stand for conditions, and
subjects for each condition are averaged together.
Version 4.0602241 February 24, 2006
1. When loading some NIFTI data, there is an ordering
problem in "hdr.dime.pixdim" and "hdr.hist.originator"
fields. It is now fixed.
Version 4.0602231 February 23, 2006
1. Modified NIFTI package to tell if the loaded NIFTI data
is converted to RAS system. (see detail in FAQ.txt)
Version 4.0602072 February 7, 2006
1. Removed unused "Group Analysis" check box from E.R.fMRI
and Blocked fMRI analysis window.
2. Made fields in PET and ERP session window look even,
because behavior data fields were removed from session
window on version 4.0512201.
3. Moved "Load Behavior Data" to a button in PLS option
frame, which looks better.
Version 4.0601271 January 27, 2006
1. "Load Onsets from a text file for this run" and "Save
Onsets to a text file for this run" submenu is added
under "Edit" menu in both E.R fMRI & Blocked fMRI "Run
Information" window.
2. When "DONE" button in above window is clicked, "Data
Directory", and "Data Files" for all the runs will be
checked, to make sure they are all filled.
3. Check session information further before creating MRI
datamat.
4. When adding more subjects for PET and ERP module, the
program will not always start from the working directory.
Instead, it will remember parent directory of the first
subject, and start to look for more subject directories
from there.
Version 4.0601251 January 25, 2006
1. Change "Save Background Image" label in result window
to "Save brain region to IMG file".
2. When display activation map, changed inaccurate display
of lower / upper_interval from ".../(num_color-2)" to
".../(num_color-1)", which is more accurate. However,
user will not notice the change, and won't be affected.
3. Fixed a bug in checking bad behavior data.
Version 4.0601061 January 6, 2006
1. Fixed a bug when read some ERP text data.
Version 4.0601041 January 4, 2006
1. Correlation Matrix is checked before decomposed. This
is only for people using PLS to analyse Structural
data, where number of data points (ROI) can sometimes
be very small.
2. Modified Seed PLS procedure "SeedPLS.txt".
Version 4.0512201 December 20, 2005
1. Removed behavior input field from "Session Window",
because it is more convenient to input behavior data
at "modify behavior data" menu under "Deselect" menu
in "Run Analysis Window".
2. In E.R.fMRI and Blocked fMRI, "Merge Data" option is
now moved to the session window.
3. If "Within Each Run" is chosen for merging data, same
condition name in different runs will be treated as
different conditions. e.g. Run1Cond1, Run2Cond1, etc.
4. All existing session file, datamat file, and result
file can still be used. However, in order to obtain
accurate result, any datamat that was created under
"Within Each Run" choice should be re-created. In
addition, all datamats that are used in an analysis
should have same number of runs, as well as same
number (and name) of conditions.
5. For "Multiple Voxel Extraction" input, the program
is now also checking XYZ with head dimension, as
well as checking XYZ with brain area.
Version 4.0511252 November 25, 2005
1. Removed "Change Current Working Directory" menu in
the start window, since the current directory is now
changed according to the session file, datamat file,
or result file you selected.
Version 4.0511211 November 21, 2005
1. Random number generator is now seeded before call.
2. Fixed a bug to create MRI single subject datamat with
any scans skipped.
3. Added menu bar to the NIFTI/Analyze embeddable viewer
"view_nii". So this independent package can also have
features like "orient", "image information" etc.
Version 4.0511161 November 16, 2005
1. "PLSgui in batch", an alternative way to run PLS,
is now available. As is explained by its name,
"PLSgui" is a Matlab program with a graphic user
interface (GUI) driven by messages from mouse and
keyboard. "PLSgui in batch" load messages from a
batch file, and automatically send them to the
program in batch. Now, you can fire batchs at the
end of a day, and the computer will create all
datamats one by one and run all analysis for you.
When you come back next day, the PLS result file(s)
is ready for you to display. ( Notes: You MUST
read all the contents in the "batch_plsgui_hlp.txt"
file carefully before using this batch feature.
Otherwise, you will more likely get either error
messages or wrong data. )
Version 4.0511071 November 7, 2005
1. Images whose cardinal planes are slightly off
Cartesian coordinates will also be loaded. However,
this approximation is based on the following
assumption: In affine matrix, any value (absolute)
below a tenth of the third largest value (absolute)
can be ignored and replaced with 0. In this case,
fields 'old_affine' & 'new_affine' will be added
into hdr.hist. If you can not accept the above
assumption, simply discard any nii structure with
fields 'old_affine' & 'new_affine'.
Version 4.0510211 October 21, 2005
1. ANT's average data (binary) and EGI's simple-binary
data can now be directly loaded for ERP module.
Version 4.0510072 October 7, 2005
1. Like ASCII files without header or with 1 line text
header, NeuroScan average data (binary) can now be
directly used as subject files to create datamat for
ERP module.
Version 4.0509271 September 27, 2005
1. Added neighbors' XYZ location to the _rf_plot file.
Version 4.0509261 September 26, 2005
1. Output standard deviation and "Number of neighbors" to
the _rf_plot file.
2. Display "Number of neighbors" in the RF window.
Version 4.0509221 September 22, 2005
1. Added a new feature in "Voxel Intensity Response Plot"
(for PET, Blocked fMRI), and "Response Function Plot"
(for E.R.fMRI). Now, people can use average intensity
of its neighborhood voxels for intensity of the clicked
voxel. Neighborhood size is 0 by default (no neighborhood
voxel is included). If it is not 0, it represents the
number of voxels from the clicked voxel. if neighborhood
voxel is included, the average intensity will include
those voxels: A) The clicked voxel; B) The "stabled"
voxels that meet the bootstrap threshold criteria, if
bootstrap result is available; C) The cluster mask of
the current view. (Cluster mask of BrainLV View is
different from that of Bootstrap View).
2. Above feature also applied to "Multiple Voxel Extraction"
for "Seed PLS". "Voxel Neighborhood Size" dialog box will
be prompted, and it is also 0 by default.
3. Added warning message for users who would like to change
the default normalization checkbox status.
Version 4.0509151 September 15, 2005
1. PLS is now support NIFTI data format. This includes
file extension support for both single file (.nii) and
dual file (.img/.hdr); temporal dimension support (4th
dimension in the data); and data value scaling support
(Y = scl_slope * X + scl_inter). It also support some
of the sform or qform affine transform. This includes
any scaling (to get voxel_size), any translation (to get
originator), any flipping, and a few Rotation (only N*90
degrees, where N must be integer).
Version 3.0509131 September 13, 2005
1. Fixed bugs for the bootstrap of Multiblock PLS.
Version 3.0509121 September 12, 2005
1. Add messages to behavior data dismatch dialog box in
"modify behavior data menu" in "Run PLS" window.
Version 3.0509091 September 9, 2005
1. Fixed bootstrap computation for multi-groups.
Version 3.0509081 September 8, 2005
1. Fixed display problem for single LV result.
2. Fixed correlation computation for multiblock PLS.
Version 3.0508051 August 5, 2005
1. Modified "create datamat" routine and single precision
is used in most steps except calculation.
Version 3.0508021 August 2, 2005
1. Modified timestamp check for "run MRI analysis"
window. Now, user can click "Ignore all" to
disregard the fact that "one or more datamat files
are older than their session files", or click
"Stop" to re-generate datamat.
2. Modified timestamp check for "plot result" window
for all modules. Now, user can click "Proceed all"
to disregard the fact that "one or more datamat files
are newer than their timestamp stored in the result
file", and update all timestamp information in result
file. User can still click "Stop" to re-generate
result file.
3. Fixed a bug in creating ERP datamat, which was
introduced in on July 28, 2005.
Version 3.0507281 July 28, 2005
1. For Multiblock PLS analysis, the conditions for
behavior block can now be deselected. It is under
the "Deselect" menu of the PLS Analysis window,
and in a dialog box of command-line PLS.
2. Fixed the display of Datamat Correlations Plot
for Event Related fMRI.
Version 3.0507111 July 11, 2005
1. Added "Single Subject" option when creating MRI
datamat. When this option is selected, each onset
will be treated as an entry of the datamat. So, the
numbers of onset must be the same across conditions.
Version 3.0507053 July 5, 2005
1. Modified call to Matlab command "uigetfile/uiputfile"
to make the code competible with Matlab version 7 as
well as Matlab version 5 & 6. This is because Matlab
version 7 will automatically append filter suffix to
the file name even we only need a prefix.
2. Removed locations for "uigetfile/uiputfile" dialog
box. This is because Matlab version 7 changed the
style dramatically, and it is not competible with
earlier version any more. This only affect program
running on Unix or Linux computers, and the dialog
box on Unix or Linux computer is always located at
top left cornor now.
3. Fixed a bug for MRI task analysis when people using
session file with behavior data.
4. If "Save Datamats" is checked when run MRI analysis,
the st_datamat variable is now saved in group cell.
Version 3.0507042 July 4, 2005
1. Changed file name for multiple voxel extraction.
Since the stacked voxel data file now use the same
prefix as you entered, it won't get overwritten.
2. Updated "SeedPLS.txt" file.
Version 3.0506301 June 30, 2005
1. Added Multiblock PLS analysis feature for all the
modules of PLSgui and PLScmd.
2. Reverse Version 3.0504055, so for Blocked fMRI,
"Normalize data with ref. scans" is now set back
to be selected by default. This is because if we
unselect this option, the brain scores can not
be distinguished between conditions.
Version 3.0506161 June 16, 2005
1. Removed old submenu "Export data for behav analysis"
in the brain score and response window. To perform
SeedPLS, please always extract data from "Multiple
voxel extraction" submenu, and follow "SeedPLS.txt"
document.
Version 3.0506141 June 14, 2005
1. Modified progress bar, so it potentially could be
canceled in the middle. (not applied here).
2. Modified load_avw, so it speeded up.
Version 3.0506131 June 13, 2005
1. Added tooktip for P-Value and Threshold in result
window.
Version 3.0505191 May 19, 2005
1. Fixed a bug in creating cluster report for Sagittal
View Plot and Coronal View Plot.
Version 3.0505161 May 16, 2005
1. Fixed a bug in ERP condition merge.
Version 3.0505041 May 4, 2005
1. Fixed a bug in reading certain EEG/ERP file.
Version 3.0504281 April 28, 2005
1. Progress bar can now be minimized.
Version 3.0504241 April 24, 2005
1. Reversed the previous change back, and disabled the
display of Talairach unit. This is because that
whether or not to display Talairach unit really
depends on how the brain image itself was registered.
If the brain image was registered in Talairach space,
the voxel is called Talairach voxel. If the image
was registered in MNI space, the voxel is called
volume voxel. Only in the situation when the image
is registered in one space, and wants to be displayed
under a different space, the conversion is required.
Both tal2mni and mni2tal functions are still included
in PLS package, so people can use them whenever
there is such needs.
2. Modified "Edit Condition" window. Now, if there is a
valid condition name entered in the condition name
field, it will be accepted when you click the "Done"
button, even if the "Add" button was forgot to click.
In addition, the heading blanks and the tailing
blanks will be removed from the condition name when
adding conditions.
3. Change label name from "Stim. #1" to "Subj. #1" in
the response function window for fMRI and ERP.
4. By default, "Normalize data with volume mean" will
not be selected for MRI create datamat window.
Version 3.0504221 April 22, 2005
1. When display PET and MRI results, Talairach unit
can now be displayed and selected besides MNI unit.
Version 3.0504211 April 21, 2005
1. Updated FAQ and help file for the multiple-run MRI
study that do not have all the conditions for every
runs.
Version 3.0504153 April 15, 2005
1. Axis will not be shown when the click of response
function is anywhere outside the brain.
2. Changed EEG read file name.
3. Updated 3V files.
Version 3.0504141 April 14, 2005
1. Fixed a display bug for response function when the
first click is anywhere outside the brain.
Version 3.0504132 April 13, 2005
1. Fixed a bug for MRI response function when datamats
have different coords.
Version 3.0504121 April 12, 2005
1. Fixed a bug for 3D background image.
Version 3.0504081 April 8, 2005
1. Reduced a loop in ERP display routine to improve the
display speed.
Version 3.0504055 April 5, 2005
1. Change label name from "Normalize data with baseline"
to "Normalize data with ref. scans" for fMRI datamat
creating window.
2. For Blocked fMRI, "Normalize data with ref. scans" is
now set to "unselect" by default.
Version 3.0504041 April 4, 2005
1. Changed AVW file name and updated 3V files.
Version 3.0503301 March 30, 2005
1. Changed label name from "Canonical" to "Temporal".
Version 3.0503291 March 29, 2005
1. Modified file menu function, so any window can call it
easily by providing the window's handle. New features
like copy to clipboard, print preview etc are also
included.
Version 3.0503171 March 17, 2005
1. In order to load results generated using Matlab 7 on
earlier versions of Matlab, a special Matlab 7 switch
must be included during the saving process. Since such
a switch is not coded in the package, a small program
called 'matlab7to5' is included to covert the .mat files
generated from Matlab 7 to be loaded on earlier versions
of Matlab that are above Matlab 5.
Version 3.0503161 March 16, 2005
1. For MRI 'Generate Datamat' window, if behavior data is
modified, user will be prompted to save data. User can
choose to save the behavior data or not.
Version 3.0503141 March 14, 2005
1. Fixed a bug in MRI result saving, when the result path
contains empty space.
Version 3.0503092 March 9, 2005
1. Fixed a bug to display the skewed result data.
2. BrainLV threshold for all modules are now initially set
to: (abs(max_blv) + abs(min_blv)) / 6.
3. Modified cardinal plane view, because most people seems
like the scroll bar in this new positions.
Version 3.0502181 February 18, 2005
1. Fixed a bug in the code that is caused by the precision
of Matlab, and modified other related files.
2. Prestim_baseline in ERP session window will follow the
digitization interval (if available), and make itself
evenly dividable by digitization interval.
Version 3.0502011 February 1, 2005
1. The "percentage of minimum different subject number"
dialog box is moved before permutation loop starts.
Version 3.0501311 January 31, 2005
1. Fixed a frozen bug in boot_order function.
Version 3.0501181 January 18, 2005
1. Original un-resampled order (sequential index of stacked
datamat) should never be included in perm_order, because
we only compare permutation result other than the original
pattern.
2. For boot_order, because all analysis have already been
included in the accumulation, except "mean-centering",
the Original un-resampled order (sequential index of
stacked datamat) should not be included in the boot_order
except for "mean-centering".
3. Add one more input parameter for "rri_boot_order", so now:
1) list of number of subjects in groups
2) number of conditions
3) number of samples
4) switch to control whether the boot_order
includes an original un-resampled order
Version 3.0501171 January 17, 2005
1. Reversed the change made in Version 3.0412081 on December
8, 2004, because the "rri_boot_samples.m" only return the
boot samples with specific different subjects. I need to
modify "rri_boot_order.m" in order to include more other
different subjects. So, it is correct to have 81 bootstrap
samples for 5 subjects with 3 minimum different subjects
in version before December 8, 2004.
2. Added a feature to let user choose the "percentage of
minimum different subject number". By default, bootstrap
must include at least 50% (i.e. half of the subjects).
The percentage can go from 30 to 70 percent.
3. Input parameters for both "rri_boot_order" and "rri_perm_
order" are now the same: 1. list of number of subjects in
groups; 2. number of conditions; 3. number of samples.
Version 3.0501111 January 11, 2005
1. Command line PLS program is released. The result is the
same as the PLSgui, but it is more simplified because we
restrict the datamat in "subject-in-condition-in-group"
format. By taking away the fancy result rendering part
and complicated subject stacking part (especially for
fMRI and Blacked fMRI), the code is much easy to read
Unused codes are properly removed and the codes are
detailly commented. It can be used to validate PLSgui
result, or might be of interest to some other people
who may want to port it to other platform.
2. Added bootsamp/permsamp to boot_result/perm_result for
all the modules.
Version 3.0501101 January 10, 2005
1. The boot order in the following scenario was incorrect:
fMRI/BfMRI mean-center/no-rotate with any datamat created
under "with each run only" option. It has been fixed now.
2. Fixed several bugs like posthoc file validating etc.
Version 3.0501061 January 6, 2005
1. In fMRI and Blocked fMRI session edit window, the
Run Information contents are checked when DONE
button or previous (next) button is clicked.
Version 3.0412081 December 8, 2004
1. Using Uril's "rri_boot_samples.m" to generate bootstrap
order. For 5 subjects with 3 minimum different subjects,
there will be 60 bootstrap samples, instead of 81.
Version 3.0412061 December 6, 2004
1. For "Multiple Voxel Extraction" under "Windows" menu
of PET, fMRI and Blocked fMRI module, it now reports
any entry in the voxel location file that is not
inside the brain region.
Version 3.0411221 November 22, 2004
1. When creating datamat for PET, fMRI or Blocked fMRI,
user is now allowed to consider all voxels as brain
region, by select "Consider all voxels as brain"
checkbox bedises the threshold editbox in "Create
Datamat" window.
2. For fMRI and Blocked fMRI, Onsets field and/or Length
field are checked to make sure they are not empty or
not match when "Done" button is clicked in "Run Info"
window.
Version 3.0411191 November 19, 2004
1. Fixed a bug of saving displayed image into another
directory.
Version 3.0411051 November 5, 2004
1. Fixed a bug in Blocked fMRI BootStrapdisplay.
Version 3.0411041 November 4, 2004
1. Modified "Contrast" edit window and "Non-Rotated Task
PLS" routine for all modules. So, it can take different
contrast for different groups now. That means, if you
have 2 groups and 3 conditions, you need to put 6 rows
in the contrast data. First 3 rows belong to Group 1,
and next 3 rows belong to Group 2.
Version 3.0410292 October 29, 2004
1. Added a new feature to allow user to use Analyze images
in any orientation for PET, E.R.fMRI and Blocked fMRI.
In "Create Datamat" window, a new button named "Check
image orientation" is added beside the "Create" button.
Once you click this button, the 3-View of one of the
subject images will be displayed in the "Change Image
Orientation" window, and you can re-orient it by click
the "Re-orient" button. Once you click the "Re-orient"
button, it will ask you to input the orientation of the
CURRENT DISPLAYED image. If you did not get the correct
orientation, you can do as many times as you want to
make it standard Analyze orientation, i.e. from Left to
Right in X orientation, from Back to Front in Y, and
from Bottom to Top in Z. If you closed the "Change Image
Orientation" window, you can re-open it by click the
"Check image orientation" button in "Create Datamat"
window again.
For people that already generated the result file in
wrong orientation but did not correct it during creating
datamat, we provided axial view of "Convert Orientation"
(under "Image Rotation" menu in the result window) only
for PET and Blocked fMRI. However, we do not recommend
people to use this limited patch. Instead, we recommend
people to use the feature in "Create Datamat" window to
correct the orientation during creating datamat.
Version 3.0410201 October 20, 2004
1. Removed (uV) sign from the legend axis for ERP Electrode
Salience window.
Version 3.0410151 October 15, 2004
1. Modified the save of session file and datamat file. It
now prevents users from saving to a filename other than
_PETsession.mat, _BfMRIsession.mat, _BfMRIdatamat.mat,
_PETdatamat.mat, _fMRIsession.mat, _fMRIdatamat.mat,
_ERPsession.mat, _ERPdatamat.mat.
2. Since we only read .mat from the current directory,
which can be changed through "Change Current Working
Directory" item under "Tools" menu in the first PLS
window, there is no need for another "PLS Working
Directory" in the session window. Now, this field has
been removed from all modules, and the path is
automatically set to the current directory.
Version 3.0410061 October 6, 2004
1. Fixed data path bug.
Version 3.0409301 September 30, 2004
1. Added following features for session windows. However,
please keep in mind that you are NOT required to modify
paths session files after you moved data from one
location to the other, unless you would like to modify
the contents of the session file. This is because that
"Run Analysis" and "Show results" only read file from
the current directory.
2. Added a feature in the Session windows to let users
change old data (image, EEG etc.) path to new data
path, as well as the change of new session path for
*session.mat file. When users click "Change Data Paths"
under "Edit" menu, the "Change Path" window will pop
up, and users can change both session path and data
path. Please see the detail and the restrictions in
FAQ.txt file.
3. The program will also do a preliminary scan for the
first run (or subject for PET & ERP) sub-folder. If
the path is invalid, it will diplay a message at the
bottom of the session window, and prompt users to go
to "Edit" and "Change Data Paths" menu.
4. "Change PLS Path" button in the first PLS window is
removed, because this program will only look current
directory for "*datamat.mat", and "*result.mat" when
users run analysis and show Results.
5. Default value of "Number of charactors for subject
initial" in "Edit Subject" window for ERP and PET is
set to -1. This way, the consistency of subject file
name convention will not be checked in the Subject
Detail window (when clicking Add or Edit). If this
number is not -1, please check Help and the FAQ.txt
for details regarding to the consistency. In addition,
this value is now saved to the session profile, so
it will be remembered when the session profile is
loaded next time.
6. Fixed several bugs.
Version 3.0409152 September 15, 2004
1. Added "Save Datamat As" feature in ERP "Modify Datamat"
window. So datamat can be saved into a different name
with (or even without) any modification. The datamat
with new name will still point to the same data file.
We did this because the data file is usually much larger
than datamat file. This way, several different datamat
files can point to the same data file (reservoir).
2. Added Bootstrap display for ERP correlation window. The
"BootStrap options" item is also added into its "Tool"
menu.
3. Substituted "Plot Canonical Scores" with "Plot Canonical
Correlations" for ERP behavior PLS result.
4. Disabled false warning message in result file that does
not store the timestamp information.
5. Removed redundant file pet_bootprocrust.m.
6. Fixed a bug in detail window of ERP correlation.
7. Fixed a bug that used wrong data path.
Version 3.0408201 August 20, 2004
1. In ERP result window, "Spatiotemporal Correlations" is
added under "View" menu.
2. In ERP result window, wave selection box like "All Cond",
"All Subj" etc is added in "Display Options" window of
"Subject Amplitude" view, "Average Amplitude" view, and
"Spatiotemporal Correlations" view.
3. "Deselect" option is added in ERP "Run PLS Analysis"
window.
4. In "Edit Behavior Data" window, "remove selected behavior
name" option, and "Save current behavior data" option has
been added.
5. Timestamp information is imbeded inside the result files.
The program will automatically check for the timestamp
integrity for datamat file (and also session file if MRI),
and will prompt with a pop-up window if necessary.
6. Fixed several bugs.
Version 3.0407291 July 29, 2004
1. Fixed an axes limit problem for behavPLS in correlation
overview window.
Version 3.0407283 July 28, 2004
1. Also check the valication of the contrast file after
click "Run" in the "Run PLS Analysis" window.
Version 3.0407271 July 27, 2004
1. For "Non-Rotated Task PLS", non-linear contrasts and
non-orthogonal contrasts will be accepted, but a
warning message will be prompted.
2. For "Non-Rotated Task PLS", display all LVs when plot
singular value or crossblock covarience.
Version 3.0407261 July 26, 2004
1. Added "Non-Rotated Task PLS" option to run non-rotated
version of Task PLS Analysis.
2. "Using Helmert Matrix" PLS Option has been completely
removed from the "Run PLS Analysis" window. Instead, it
is added under the "File" menu of contrast window.
3. When running Bootstrap Analysis, the bootstrap result is
now checked and replace meaningless data with 0. Thus,
reduced the display crash when rendering the bootstrap
result.
4. Related Documents are modified to represent this new
release.
Version 2.407141 July 14, 2004
1. Modified program so it now only requires matlab toolbox.
Version 2.407131 July 13, 2004
1. In PLS start window, when the "Show PLS Result"
or the "Run PLS Analysis" button is clicked, the
program will assume that all the related matlab
files (*.mat) are sitting in the current directory,
thus, avoid trouble when those matlab files are
copied between systems. In other words, people do not
need to use the "Change PLS Path" button any more
when copy those matlab files between systems. If the
related matlab files are not sitting in the current
directory, people can use the "Change Current Working
Directory" submenu under "Tools" menu in this start
window to change the directory containing those matlab
files as current directory.
2. "Save display setting" for result window dialog box
will not be prompted out every time when people change
the display setting and close the result window. Instead,
program will now read status from "Save display setting"
submenu under "Tools" menu in the start window to decide
whether save the display setting for users. In addition,
when people open start window, program will not prompt
"Create PLS Profile" message, and by default, status in
"Save GUI position" submenu under "Tools" menu will be
set to "Off" at beginning.
3. In ERP "Edit Channel Order" window, added number beside
"Channels:" label and "Selected Channels: " label, and
implemented multiple remove in "Selected Channels" panel.
Version 2.406181 June 18, 2004
1. Fixed a bug in Blocked fMRI RF Plot when prefix of
datamat is different from that of session file.
2. Added a warning window after the datamat saved into
a different prefix, and the "datamat prefix" in
session file is updated.
Version 2.406111 June 11, 2004
1. When the "Cluster Mask" item under "Report" menu is
checked, both "Save display" and "save result" under
"File" menu will save the current masked image. When
"Cluster Mask" is unchecked, they will save the
unmasked image.
Version 2.405101 May 10, 2004
1. Add a "Create Figure" sub-menu under 'Window' menu
in "3 Cardinal Plane View" window.
Version 2.404132 April 13, 2004
1. Used standard normal distribution to calculate p-value
in Cluster Report.
2. If any column of behavior data contains the same data
for each group, program will stop proceed, and prompt
error message.
Version 2.404081 April 8, 2004
1. Added merge conditions option in creating datamat
window for both PET and ERP modules. (E.R.fMRI and
Blocked fMRI modules already have the option).
2. Prompted file name after save or export a file in
Cluster Report window.
Version 2.403301 March 30, 2004
1. Fixed a cond. labelling bug in PET brain scores plot.

plots have own Y scales.
Version 2.403031 March 3, 2004
1. Worked around to make program not crash in extreme
situation when max_blv(bsr) = thresh = 0 or
min_blv(bsr) = thresh = 0.
Version 2.403023 March 2, 2004
1. Fixed a bug that was introduced in on Jan. 9, which
can cause PLS result display frozen on some PC.
2. In '3 Cardinal Plane view', XYZ & Value are updated
with the 3 sliders now.
Version 2.402271 February 27, 2004
1. Added a feature to display all three cardinal planes
for the PLS result data. To view all three cardinal
planes, click '3 Cardinal Plane View' submenu under
'Windows' menu.
Version 2.402181 February 18, 2004
1. Modified 'fmri_plot_hrf', so it can read session file
with empty onset data in one or more conditions for a
single run.
Version 2.402131 February 13, 2004
1. Modified 'fmri_plot_hrf', so it can read both old and
new fMRI session file.
Version 2.402121 February 12, 2004
1. Saving result to an IMG file now has two different ways.
When saving 'BLV (or BSR) result to IMG' file, it only
saved the BLV data (or BSR) data to an IMG file, and
does not include colormap or background image. When
saving 'Current Display to IMG file', it will include
colormap and background image.
Version 2.402111 February 11, 2004
1. Modify Edit Runs, so the MRI session file is consistant
no matter using text file to input onset data or enter
onset data manually.
Version 2.402101 February 10, 2004
1. Reversed 2 changes made in Version 2.402051 (1 & 2).
So we still export the whole time series, instead of
only export the active time lag.
2. Cluster Report can be saved in tab-delimited .txt file,
as well as in matlab .mat file.
3. Made XYZ(mm) field editable.
Version 2.402051 February 5, 2004
1. Changed the XYZ text box to edit box, so the current
location can be set from this text box, rather than
go to 'Set cluster report options' menu. For Event
Related fMRI, [Lag X Y Z] is used, and for others,
[X Y Z] is used.
2. The data export in response function and Multiple
Voxel Extraction will now only export the data in the
corresponding lag number.
3. SeedPLS document modified because of above change.
Version 2.402021 February 2, 2004
1. Updated MRI datamat creation help file.
2. Program can now set current location based on value
in 'Current location (/ Current lag)' field(s) under
'Set cluster report options' submenu under 'Report'
menu. The result is the same as clicking the specific
location.
Version 2.401281 January 28, 2004
1. When saving cluster report, if the suffix is not
entered, program will now automatically add one.
2. When loading cluster report, it looks for proper
suffix now.
3. Changed the representation of cluster mask. Instead
of putting a marker on voxel, now it only displays
the clustered voxels.
4. All parameters in the create datamat window are now
stored in a structure named 'create_datamat_info'.
Version 2.401191 January 19, 2004
1. Added HRF Plots in MRI Run information window.
2. Created help file for this plot.
3. Added 'Save Figure' in File menu for several windows.

1. For fMRI Response Functions Plot and Canonical Scores
Plot, the Average plots is now scaled independently.
2. In addition to the HRF correlations, as for task PLS,
HRF Response Function is now also plotted for Behav
PLS.
3. Modified Seed PLS document 'SeedPLS.txt', and allow
user to use 2 different way to input extracted behav
data.
Version 2.312222 December 22, 2003
1. Change Pointer to 'Watch' while waiting for data
exporting from 'Multiple Voxels Extraction'.

same amount of rows as 'datamat' variable in datamat
file.
Version 2.312162 December 16, 2003
1. Added color selection for Crosshair.
Version 2.312151 December 15, 2003
1. Added a Point-to-Text button for ERP plotting subject
amplitude detail. The selected point will be appended
into a text file entry after click this button. The
file name of the text file will use the same prefix
and ended with '_ERPdetail.txt'.
Version 2.312081 December 8, 2003
1. Modified MRI datamat generation function, so it will
not use large memory to hold an onset of data.
Version 2.312041 December 4, 2003
1. Fixed a cond. labelling bug in PET brain scores plot.
Version 2.312011 December 1, 2003

Version 2.311252 November 25, 2003
1. Fixed a bug for voxel selection, so the voxel location
is correct now.
Version 2.311211 November 21, 2003
1. Re-Scale HRF & Canonical Plots to make them the same
across all conditions & groups.
2. Add stable display for HRF, if it is a bootstrap
analysis.
Version 2.311201 November 20, 2003
1. In MRI session window, Merge Condition can now take
conditions with different numbers of onsets
Version 2.311191 November 19, 2003
1. Added a new electrode system for ERP/EGI
Version 2.311113 November 11, 2003
1. Make Onset Timing Plot a Gaussian Curve, from Onset
to Onset plus 16 seconds.
2. Add (TR) after 'Event Onset' and 'Block Onset'.
Version 2.311111 November 11, 2003
1. Added an Onset Timing Plot menu in MRI Edit Runs
window to display onset timing for all conditions.
2. In ERP Create/Modify Datamat window, Analysis
Start/End Time now accept numbers that can not be
evenly divided by Digital Interval and then round
to the closest number that can be divided by
Digital Interval.
3. Move Zoom menu of ERP Plot window to the right of
Edit menu.
Version 2.310301 October 30, 2003
1. Allow user to apply STD on their MRI data, and
hopefully this could remove some spikes noise
from the brain region. To do this, the MRI datamat
must be created first, and then choose 'Apply STD
to Datamat' from 'Datamat' menu in Session Profile
window.
Version 2.310261 October 26, 2003
1. Integrated the MRI convert_task into PLS. So instead
of prompting re-run MRI task analysis, it will prompt
and ask for the new result file name.
2. removed the convert_task M file.
Version 2.310242 October 24, 2003
1. Instead of re-run MRI task analysis, you can now
type: convert_task(oldfile, newfile); to convert
your old fMRI/BfMRI task analysis result file to
the readable new result file.
Version 2.310241 October 24, 2003
1. Session Profile list file can not be save and load
in MRI Select Session Profiles window.
2. Corrected MRI Brain Scores Plot. However, all the
Task fMRI/BfMRI analysis must be re-run to include
the correct Brain Scores row index information.
3. Fixed bug that not saving st_datamat.
Version 2.310231 October 23, 2003
1. Added new feature to display the subject ID by click
the marks for MRI brainscores x designscores plot.
Version 2.310153 October 15, 2003
1. Added export for Correlation RF.
2. For Datamat Correlation Plot, now it can load / save
background image, and save Datamat Correlation image.
