You would want to edit the wm.mgz to fill the ventricles in if the
surfaces are not accurate. So from your picture, I would say the surfaces
do not look accurate in the right hemisphere since they are being pulled
into the ventricle.

Hi,
I recently started using freesurfer and finally processed my first subjects
with all three recon steps (using the latest version).
Checking the white matter volume I recognized that all my scans have the
same issue:
The lateral ventricles aren't filled entirely but there are some black spots
within the ventricles..in the tutorial is written that one should handle
this in a described way but I was wondering if this is necessary when recon3
was sucessful without any errors.....
Does anyone have experience with that? (see attached picture)
Thanks a lot,
Dorit Kliemann
