Hi all,
What is the best way to calculate total brain volume? It seems that there are multiple ways to do it--mris_volume and mris_wm_volume, add up the structures in the aseg.stats and ?h.aparc.stats files, or using the BrainSegVol or BrainSegVolNotVent from aseg.stats.
What do you recommend?
Thanks! Justin
Hi Justin, It partly depends on what exactly you want when you say "brain volume". Do you want a measure of estimated intracranial volume (intended to be independent of atrophy)? A measure of gray matter + white matter + ventricles? Or only gray matter + white matter? Do you care whether the cerebellum is included or not?

Dear experts,
I would like to extract certain sulcal ribbons from brain surface and create a probability map for each sulcus type. I was wondering if freesurfer generates sulcal ribbons (or sulci curves on the flatten surface) in the subject space.
Thank you, Amir

no, sorry, we don't generate sulcal ribbons, although it wouldn't be too hard to generate a skeleton from the flattened parcellaton

Thanks Bruce for your reply.
This is actually helpful. Could you please briefly describe how can I generate the skeleton?
Thank you, Amir
