I would use unstripped, but it probably won't make much difference. Just make sure that the registration is good.

External Email - Use Caution

Dear Freesurfer experts,

I was wondering if there is any recommendation on the PET input file for partial volume correction using mri_gtmpvc? Should I use a non-skullstripped SUV or a skullstripped SUV? If a skullstripped SUV can be used, would a tight (just aparc+aseg binarized) or a lenient (e.g. aparc+aseg binarized and dilated by 2mm) mask be better? I am interested in using the GTM regional values. Thank you for your help!

Best wishes, Jane
