Hi Pietro
it's tough to tell from a single slice, but I would guess that the wm of
the superior temporal gyrus isn't well segmented resulting in a topological
defect that cuts it off. Can you put control points in the wm there? Look
in the wm.mgz and see if the gyrus connects and disconnects repeatedly,
which is the hallmark of a topological defect. If you can't figure it out,
feel free to upload the data and I'll take a look.
cheers

Hi freesurfers,
I have a problem editing a topological defect given that it is represented by
cortex non included within the pial boundary
without white matter in it. The problem is I can't use white matter to place
control points and/or edit voxel in the aux
wm.mgz volume...
I'm attaching an image...
the area I'm talking about is indicated by green arrows.
Thanks in advance,
Pietro
