Hi,

I am running a behavioral analysis in PLS with PET data - 11 subjects, 4 conditions and a subjective rating score for each scan.  I created a PETdatamat.mat file with the scans, loaded it into "Run PLS...", selected the "Behavior PLS" option, loaded the subjective rating scores as a text file with each rating in its own column and with only 1 rating per scan.  I then selected "Run from GUI" and the "Saving PLS Result" dialog box pops up, I saved the PETresult.mat and the "Loading datamat" box starts loading, but then stops roughly 1/4 the way through and I get the following errors in my Matlab dialog box:

Warning:  Future versions will return empty for empty == scalar comparisons.
ERROR:  There are no common voxels found.
Warning:  One or more output arguments not assigned during call to 'pet_analysis'.
Warning:  Reference to uninitialized variable elapsed_time in pet_analysis_ui/ExecutePLS at line 1919.

I was wondering if you have an idea where I am making a mistake.  Thank you very much for your help.
