Hi Miranka, why not create a contrast that computes this difference? When you do this, there will be a gamma.mgh file in the contrast directory that has this information in it. doug On 04/12/2012 02:06 PM, Miranka Wirth wrote: > Dear freesurfers, > > I am trying to create a map that shows the ve

[Freesurfer] group difference thickness map

2012-04-12 Thread Miranka Wirth
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 tha
