Hi,
I am a new user of FreeSurfer and trying to figure out gray matter segmentation.
A volume that I extracted from aparc+aseg.mgz using mri_segstats did not match the volume reported in /stats/ text files (for example, aseg.stats, rh.aparc.stats). Even without specifying a mask in mri_segstats, there's always a discrepancy of 100 voxels or something. Where do the numbers in /stats/ files come from? Aren't they from aparc+aseg.mgz?
Thanks!
