Is this for an ROI-based study or a map-based study? For ROI, we use the GTM, and it PV corrects for all structures (including WM and CSF). For map-based, we use MG. MG removes WM (and CSF) entirely. In theory, it can be run in a way to keep WM and throw GM and CSF away, but that is not implemented. Does this answer your questions?
