It will be easier not to use make_average_subject. Just use mris_preproc
as if you are doing a group analysis. See
https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/GroupAnalysisV6.0
The output of mris_preproc (lh.gender_age.thickness.00.mgh) can be
compressed to an average with
mri_concat lh

Dear Doug,
Thanks for the fast reply.
Well we calculated the measures surface area (SA) , thickness (THK), volume
(VOL) in each participant (in surf folder) of our groups and evaluated the
differences between them using Monte Carlo.
Now we wanted ju
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?

Dear 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 m
