Hello SPMers, This is more of a MATLAB/programming question than a SPM one, probably. I am trying to write a script to analyse my RS-fMRI dataset recursively for all the subjects. The problem is that when I have to select the VOIs in order (PCC, mPFC, LIPC, RIPC), I need to create a 4xNN character (NN being the length of the path to the .mat files for the VOIs). This is done in the GUI individually and the user basically has to select the VOIs one by one, in order, which leads to creating a character (called P) and sts (a binary status for the job being successful/unsuccessful): [P, sts] = spm_select([1 8],'^VOI.*\.mat$',{'select VOIs'},'',swd); I was wondering whether there is any other way of doing this to create the variables P and sts, in the script and include the four different regions in order.
