Is this true of the aseg files as well?  I tried *double-checking* the
mris_anatomical_stats by using the aseg file in MatLab (assigning values
to the voxel-intensities, counting them up, etc, etc) and the numbers came
up different.  Is that why?  Probably not the best method now that I think
about it...  Thanks Doug & Bruce.

It is only cortical. And you don't want to use ?h.ribbon.mgz as this is
quantized to 1mm^3 and will be less accurate than mris_anatomical stats.

Hi,

I am attempting to assess (& compare) total cortical gray matter volume
in
a series of subjects (schiz vs. control), and was wondering if the
tabular
mris_anatomical_stats gm output consisted of only cortical gm, or
included
subcortical and other nuclei as well.  I've searched the wiki, articles,
and listserve archive with not much success; I get the sense that it is,
but want to make sure.  Additionally, what is shown in the ?h.ribbon.mgz
files appears to be exactly what I am looking for.  Is there any way to
run the mris_anatomical_stats command on these files (use mris_convert
maybe)?  Thanks in advance.
