Dear Freesurfer Developers

I am doing an ROI--based amyloid PET scan analysis. I have completed all of the 
steps from the PetSurfer wiki. I now have the preprocessed, averaged, 
resampled, smoothed PET data in MNI305 space which is constrained to the 
subcortical gray matter mask.

How do I extract mean intensity within all of the subcortical ROI?

Thank you!

Warm regards,
