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!
