Hi,
I would also like to re-create the brain score vs. behaviour data plot, but this time for a block fMRI study. I tried to type the function bar(lvcorrs(:,1));
into matlab as you suggested in the last post, but it said that lvcorrs was undefined function or variable.
What I would like is the numerical values of the behaviour and brain score for each individual subject to re-create the plot.
If I need to do this in matlab rather than the gui, please write detailed instructions since I am not very familiar with the matlab or PLS program.
Thanks,
Erin

Both variables are stored in the results file, but you will need to load the file into MATLAB and access the fields from the command line:
in MATLAB (the >> is the MATLAB prompt,)
>>load myresults_BfMRIresult
(replace 'myresults" with the actual filename for your results file)
>>save brainscores.txt b_scores -ascii
>>save behavdata.txt behavdata -ascii
Once you exit MATLAB you will have two text files, brainscores.txt and behavdata.txt, that you can import into your favorite plotting package.
have fun

Just a small correction:
Rather than b_scores, which is used for Behavior PLS part of Multiblock PLS, brainscores is used for Behavior PLS.
So, it should be
>>save brainscores.txt brainscores -ascii

Dear Randy and Jimmy,
Thanks so much for your help. Just to clarify, the data is organized so that each subject in each latent variable is a row (organized s1lv1, s2lv1,... sxlv1, s1lv2, s2lv2,....sxlv2...etc.) and the columns are the different conditions?
Thanks,
Erin

Each column stands for an LV, and the sequence of rows should always be subject-in-condition-in-group. i.e.:
g1c1s1LV1 g1c1s1LV2
g1c1s2LV1 g1c1s2LV2
g1c2s1LV1 g1c2s1LV2
g1c2s2LV1 g1c2s2LV2
g2c1s1LV1 g2c1s1LV2
g2c1s2LV1 g2c1s2LV2
g2c2s1LV1 g2c2s1LV2
g2c2s2LV1 g2c2s2LV2
