Hi Doug,

Thanks for the clarification. According to the PetSurfer guide, it is stated 
that there are “ways to customise this segmentation to use ROI definitions”. 
How may I go about doing that? Appreciate your help.

Best Wishes,
Elijah

what do you mean? You can only get gtm stats from the parcellations that  
you have used during the process. You can't get new values at the end.  
If you want to use different ROIs, then you need to run gtmseg again  
with a different parcellation, then run mri_gtmpvc with the new gtmseg
