Hi Derin,
so I guess I would use brain volume as the surface volumes of the gray and the white + subcortical volumes (and cerebellum).

For one of our projects. We're using cortical gray matter for another (which I wanted to clarify).

Then is there a reason to use mris_volume when I can just do mris_anatomical_stats and forget the math?
So, if I take the ?h.pial volume then add in the subcortical structure volumes from aseg.stats (as you mentioned earlier) then that would give me the estimated whole brain volume? Thanks Bruce!

you would need to subtract the ?h.white volume from the ?h.pial to get gm volume

Not sure if this went through the first time yesterday, here it is again. Thanks.
I've noticed that the gray matter volume output from mris_anatomical_stats (lh) vs. mris_volume (lh.pial) differs. Am I missing something? Do I need to run mris_volume for a different surface? Thanks.
