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;
