Hi Checking the white matter segmentation of a subject I found the problem atacched (blue arrow in the axial, sagital and coronal views). I used controls points but the problem remains. Any idea? Thanks Abel
Hi Abel,
it looks like either damaged or very thin parahippocampal white matter, which causes an apparent change in topology. Probably the topology correction is making the wrong choice (cutting instead of filling). I would fill in a few voxels to make sure the strand stays connected all the way out, then run autorecon2-wm
cheers, Bruce

p.s. you will also probably want to remove some of those control points, as they look like they are partly or fully in the gray matter, which will mess things up.
