Dear freesurfers,
I am trying to create a map that shows the vertex-wise magnitude of thinning (f.e.) between two groups, similar to Fig5 in Dickerson et al., 2009. I know how to extract the group-average thickness map from the beta.mg (mri_convert beta.mgh group1.mgh --frame 0 etc.), assuming that this is the way to construct the figure. Is there an easy way in freesurfer to compute the difference between these to group-average maps?
Thank you for sharing. Miranka
