I tried that, too and it seemed to work. I extracted the ROIs from ?h.aparc.annot and merged them into a single label with mri_mergelabels then I ran mri_glmfit. Now I am not sure I used the correct command to mask the search:
mri_glmfit --y lh.g2v0.thickness.15.mgh --fsgd g2v0.fsgd dods --C group.diff.mtx --surf fsaverage lh --label lh.22mask.label --glmdir lh.group_diff_g2v0.glmdir So I used my own label instead of ?h.aparc.annot. Does the above command look right? Thanks again! Mihaela On Fri, Jul 22, 2016 at 12:34 PM, Douglas N Greve <gr...@nmr.mgh.harvard.edu > wrote: > What was your visualization command?
