The GTM gives you values for each ROI regardless of whether it is GM,
WM, or CSF. They will probably give you similar answers, but the GTM
will be more robust.

If you want to do an ROI
If you want to do an ROI analysis using FS-based ROIs, you should do
that at the individual level. Resample the PET to the anatoimical space,
