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.
