Sorry, I don't think we have such a program. You could do it in matlab fairly easily, eg,
f = MRIread('filtered_func_data'); fmat = fast_vol2mat(f); a = MRIread('aparc+aseg'); seglist = unique(a.vol(:)); seglist = seglist(2:end); % remove segid=0 (unkown) clear roimean for nthseg = 1:length(seglist) ind = find(a.vol == seglist(nthseg)); roimean(:,nthseg) = mean(fmat(:,ind),2); end m = roimean'*roimean; On 01/31/2013 01:29 PM, Sudhin A.
