Yes I need the lh and rh cerebral WM for sure, but not just the
values, also an image.
And I need also a corrected image for the extra cerebral CSF.
How can I get that?
It will certainly do cortex. We do not have a segmentation
for subarachnoid spaces. Or are you just talking about extra
cerebral CSF? We do have a segmentation for xCSF, but it is not
the most beautiful thing in the world. For WM, the GTM will give
you a PVC corrected value for the entire lh and rh cerebral WM
(and cerebellar) segments. Is that all you need?

Dear Freesurfers,
We need to analyze PET data after correcting for partial
volume effect in the cortex, white matter and subarachnoid
space. Is Freesurfer's partial volume correction working on
all these areas or only the grey matter volume and surface?
Is there a way to use gtmseg on the white matter and outside
the pial surface?
Thanks a lot,
