1) The right panel shows the aseg voxels. The surfaces are the same in L and R panels. 2) What do the surrounding slices look like? It may be that the WM surface "fills in" more as you go along.

Dear Freesurfers,
My first attempt of this message somehow didn't make it to the mailing archive. In case it didn't go through, I am sending it again. Sorry to bother you if you received the first message.
Two things I was wondering 1) Why do the surfaces shown in the left and right panels disagree? (The right one has a lot more white matter). 2) Do I need to edit the white matter? It seems unreasonable to have +8mm thick of grey matter. If so, I will probably paint more voxels to wm.mgz.
Thank you very much!
Sincerely, Ye

I would like a second eye on my decision to edit wm.mgz. I think that the boundary between the gray and the white is unrealistic (e.g. Coronal.png). Furthermore, there is a discrepancy between -surfs and -surfs -aseg (e.g. attached coronal_aseg.png).
If I indeed need to edit these slices, which way is more preferable, adding voxels or control points?
Thank you very much!
Sincerely, Ye
