Re: [Freesurfer] How to measure the surface dimension in a mask image after mri_glmfit?

Hi Glen, you can use

mri_segstats --seg mask.mgh --id 1 --i $SUBJECTS_DIR/fsaverage_sym/surf/lh.area --o sum.dat

Dear freesurfer users

I'm wondering if there is any way of figuring out the surface size within a mask image (mask.mgh) which is generated after running a group-level GLM analysis (2nd RFX) using mri_glmfit.

As I'm thinking, this may be: number of vertex by dimension of one vertex (1mm).

But I could be wrong and let me know if anyone knows the solution.

fyi) the group analysis was performed in freesurfer sym space.
