Hi, I have a PET volume that is registered to a recon, then projected to the surface via vol2surf. I would like to pull stats for the PET using aparc regions. Should I use mri_annotation2label, then pull stats for each label? Or is there something similar to mri_segstats, ie. --annot lh.aparc.annot --in pet_surf.mgz --ctab-default --sum stats.table ? Thank you for your help! Sara
