[Freesurfer] Gray matter volumes

Hi again,

Two questions:

1). You said earlier that GM volumes from mris_anatomical_stats are more accurate than from the aseg files. Would you recommend using the surface-based GM volumes instead of the ones from the aseg.stats files? I ask because we have ~200 subjects processed for volume, but not surface, meaning no mris_anatomical_stats. If we could avoid the added processing time on these it would be helpful, but don't want to do it at the expense of accuracy.

2). What structures are calculated into "total white matter volume" under mris_anatomical_stats? Does it include corpus callosum and others? Thanks.
