Dear Freesurfers, 

I am interested us using  centrum semiovale as reference region while calculation SUVR values. Is there a way to save the unsegmented white matter [5001& 5002] during the gtmseg step ?

in other words looking for an option like this
--keep-unsegmented-WM :do not relabel unsegmented_WM as WM

Thanks,
Pradeep
