You have to run recon-all through to the end. You can then extract a GM
mask from that. You will need to register your PET image to the
anatomical (mri_coreg), map the PET into the anatomical space, then use
mri_segstats to compute the mean PET in the GM mask. Alternatively, you
may want to use
Hi Emily,
is it a volume or surface functional map? If volume, I think it should be
pretty straightforward to sample it onto the surface with mri_vol2surf
then go from there. There is probably a way to do this in SUMA also.
cheers,

Dear Gr
Do you mean cortical masks? If so, then {lh,rh}.ribbon.mgz are binary
masks. You can convert them to nifti with:
mri_convert lh.ribbon.mgz lh.ribbon.nii
