External Email - Use Caution
Hi Doug,
I have a question surrounding our attempts to extract PET binding values (BPND/DVR) which have been first transformed into FS subject space, mapped to the cortical surface using mri_vol2surf (signal averaged over the middle 80% of the cortical ribbon), and then displayed on the inflated hemisphere surfaces.
We would like to extract the average binding values from the cortical surface ROIs using the Desikan-Killiany atlas, but are unsure how to go about this. Is there a simple way to use aparcstats2table or a similar command to extract average values from surface ROIs as defined by the ?h.aparc.annot file?
Thanks!

Yes, you can use mri_segstats. Run it with --help and see Example 6, change thickness to your BPND overlay
