Dear All, Is the total white matter volume computed by mris_anatomical_stats the total volume inside the gray/white surface? Or does it exclude subcortical structures? i.e. is total brain volume = total gray matter volume + total white matter volume ? Thanks, Sasha

it's the volume of the wm.mgz, and it's deprecated. Use the various wm volumes in the aseg files (or aseg.stats) instead.

is there a way to compute the volumes contained within the ?h.pial and ?h.white surfaces?

mris_anatomical_stats will give you the volume of the ribbon. There's also a program Xiao Han wrote called mris_volume that will compute the interior volume of any closed surface. Not sure if it's in your distribution, but it's in dev (and stable3 I think)
