External Email - Use Caution
Dear experts,
in several subjects I am encountering "leak" of white surface into ventricles (see screenshot with enlarged cursor indicating the problematic area). According to my experience, editing of aseg.presurf.mgz or wm.mgz does not help. orig.nofix surface seems OK (without leak into ventricle). Could you please advise how to correct this type of error? I have also uploaded example subject (named white_surface_in_ventricles.tar.gz) to your FTP server so that you can have a look.
Regards,
Antonin Skoch
Hi Antonin
what does the orig surface look like? If it is crossing the ventricle and the orig.nofix is not, then there is a topogical defect that is causing the leakage
