you would need to add in whatever subcortical components you wanted to
include, as they are excluded from the wm volume

Bruce,
So if I downloaded the dev version of the program I could use it to get
the volumes from subjects processed with 3.0.3? And would adding these
volumes together generate the total volume I'm looking for (including
subcoritical)? Thanks!

Hi Derin,
the aseg labeling of cortical gm is not that accurate - the surfaces are
quiet a bit more so. We have a new tool for generating the estimate of the
gm and wm volume from the surfaces called mris_volume and mris_wm_volume.
I
think Doug or Nick has integrated it into the dev version of recon-all.
cheers,
Bruce

I would like to calculate total brain volume (defined as: total white,
gray, and subcortical altogether). Should I take the BrainSegVol and
minus out cerebellum and ventricles, or add the white and gray matter
volumes from mris_anatomical_stats (it seems I remember hearing that
white
matter from mris_anatomical_stats is not reliable)? Thanks.
