What do you mean by "gray matter Volume"? Do you just want a map where the value at a voxel is the fraction of GM in that voxel? What space (eg, cvs, fsaverage, mni305) are you planning to make the average in?

External Email - Use CautionDear Freesurfer Community,
I want to have an image of the average gray matter Volume in each of my 3 groups, and I did not find a good way to do it.
I easily obtained an image from the GM thickness and area by using make_average_subject in each of my 3 groups (young musicians, old musicians and old nonmusicians). Thereby in the surf subfolder I could find an image of these 2 measures.
Could anybody give some helpful hint.
I am using FreeSurfer 6.0 on an Ubuntu Machine.18.04.4 LTS.
Best regards, Georgiana
