Hi Claudia it really depends on the individual case and what's causing the exclusion. Does the wm.mgz look accurate? If so, you may have a topological defect that is being fixed incorrectly. Usually we focus on fixing the white boundary and that will also correct the pial. You can set the

Hi Claudia now I'm confused. Did you put control points in those voxels? You definitely, definitely must avoid putting them in voxels that contain anything other than WM. The pial surface will usually be incorrect if the white surface is incorrect, so the first thing to do is make sure it is

I'm sorry Bruce I'm confusing you. The fact is that those areas are labelled as WM, so I thought those were white matter, but looking with more attention at wm.mgz I did realize that they could me no WM, as you seggested me, because they are too dark. I'm new and I'm learning by trial and error.
