Hi Elisa

it's tough to tell from just the wm.mgz image. Are the voxels excluded from the pial brain or are they dura? What does the orig surface show? If the orig doesn't follow the wm.mgz and you think it should, that means there is a topological defect that was inaccurately corrected and you need to fix that cheers Bruce On Fri, 31 Jan 2014, elisa veronese wrote:

Dear all, I am trying to manually correct the segmentation result in one subject. My problem is that I am not sure if in the area highlighted with the green circle (see attached file) the volume I should correct is the brainmask.mgz or the wm.mgz. The pial boundary looks uncorrect, so I'd correct the brainmask. But those voxels seem to belong to the wm.mgz volume, as well...

Thank you. Best, Elisa
