Probably a topological defect but we would need the data to tell. Feel free to ftp it to us and we will take a look Cheers Bruce

Hi FreeSurfer community,
I am relatively new to manually editing and am having some questions dealing with editing the wm.mgz. Occasionally, white matter and grey matter are being incorrectly cut out, but I cannot edit WM voxels in the area (lh postcentral) because they are already considered WM in the heat map (but excluded from the boundary). I have attached images. How would I go about fixing this? Would control points work here?
And would the segmentation error in slices 79-81(lh postcentral) be edited by adding wm voxels (I can't really add any to slice 79)?
(This is an elderly brain.)
Thank you,
Emily
