Hello all,
We've noticed some errors in the wm and pial segmentations (see t1.png) even though the wm.mgz seems to be correct (see wm.png). Could you advise us on the best way to correct these errors?
Many thanks, Nicola
Hi Nicola, Its hard to tell from this one slice. My experience is that if you look on the wm.mgz volume up and back a few slices you'll notice a slice where there are edits to be made!

hard to tell from a single slice, but my guess would be that there is a topological problem with the wm.mgz that you need to fix manually. Feel free to send it to us if you can't figure it out.
