Do you mean you compared your TBI subjects against fsaverage? That is not proper methodology.

Dear FreeSurfer Developers:

I compared the cortical thickness, area, volume in the mild traumatic brain injury patients with health control by FreeSurFer, and found a statistic difference region in the cortex area and volume after correction. How can I extract the value of cortex area and volume for every subject in the fsaverage with the code of mri_segstats

FreeSurfer version: freesurfer-Darwin-OSX-stable-pub-v6.0.0-2beb96c

Platform: macOS High Sierra.
