Hello everyone,

I am obtaining the following error when trying to run a mean-centered PLS:

The datamats have different voxel size.
Output argument "num_behav_subj" (and maybe others) not assigned during call to
"fmri_pls_analysis>concat_st_datamat".
 
Error in fmri_pls_analysis
 
Error in bfm_analysis_ui>ExecutePLS (line 2256)
        fmri_pls_analysis(PLSoptions.profiles, [], ...
 
Error in bfm_analysis_ui (line 118)
           ExecutePLS;
 
Error using uiwait (line 81)
Error while evaluating UIControl Callback.
 
I have checked the datamats and I see the same voxel size for each participant. I am analyzing multiecho rest data that was preprocessed with AFNI's ME-ICA pipeline. Any help would be greatly appreciated.

this is probably a datamat size error, not actual voxel size. check that the images are masked identically - the dims of the datamats should be the same

HI Nancy,

I have looked at the dimensions of all the session datamats and I have the same values

can you give us some more details? That part of the code is called in behavPLS analysis, which is not a mean-centred...

did you set up a behaviour list to be loaded?

Are you using the gui or command-line?

thanks

Nancy

HI,

Sorry for the slow response. I am running a mean centered in the gui. There is no behaviour loaded.

If it matters I am using the newest version of matlab. 

Thank you for you help

try it with 2014a.. we cannot guarantee the behaviour of the gui after that version.
