Hi Brianna
yes, that would work (although you would use freeview or tkmedit).
Why do you feel you need a new atlas? Our latest version does quite well, even on subjects with very very large ventricles. What version are you running?

Hi Bruce, Would be interested in an atlas for aseg that gives total gray matter and ventricle volume. Would I be able to create an atlas based on these 30 patients with labeled volumes for just these measures? Additionally, my understanding of creating an atlas is very rudimentary - would I begin the process by running recon-all on these 30 scans and then manually editing the segmentations using tksurfer?
Thanks again, Brianna

what kind of atlas do you mean?
