Hi Meng,
no, we usually provide gray matter volumes, thicknesses and surface areas using the surfaces (although we do explicitly provide a voxel labeling in the aseg.mgz). It should all be reported in the various files in the stats dir.

Hey, all
Whether the FS only segment the white matter volume (WM - mri/wm) by default . How about the GM? If I want to get GM volume, is it a right way to use brain.mgz to subtract the wm.mgz?
Best Wishes,
