Dear Freesurfer developers,
When I was troubleshooting my data I came across an odd parcellation error that I can not place. When looking at the reconstructed surface parcellation (freeview -f {$subject}/surf/lh.pial:annot=aparc.annot:name=pial_aparc:visible=0 \ --viewport 3d) I noticed that in a large proportion of my subjects the parcellated errors are not placed correctly. Moreover, the error mostly seems to apply to the right cortex and not the left. I adjusted foto's for visual information.
I already checked the brain mask.mgz file and the rh.white and rh.pial surfaces I cannot find any segmentation errors either.
Do you have any idea what could have gone wrong and how I can correct for this?
Kind regards, Aicha
don't know. can you send these subjects to me through our filedrop? url below
