Dear all,
I have 2 question concerning edits to the pial and wm surface.
1) After editing the pial surface in the ventral temporal lobe (parts of the cerebellum were erroneously included), there were no visible changes in the pial surface after rerunning autorecon2. Is it possible that correction of the pial surface by editing/deleting voxels in the brainmask.mgz volume shows an effect in superior parts of the brain (e.g. upper parts of the dura) but not in inferior parts that are adjacent to other tissue? How do I correct errors like that? And how do I extend the pial surface anyways?
2) When deleting those exessive pixels of the cerebellum that were classified as pial surface, I obviously deleted parts of the cerebellum in the brainmask.mgz. Will this have an effect on the cerebellar volume measurements?
Thanks a lot! Best,
Ingo Wolf
