Hey, thanks for your prompt reply. 

One more question, in subject/mri folder, only the Orig.mgz and  T1.mgz adjust the AC-PC alignment of the image to be closer to MNI orientation. Because after the step of skullstrip, all volume use another origin. Is it right?

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.

cheers

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,
