Thanks Bruce. After I remove the problem voxels in wm.mgz, do I then re-run the recon from autorecon2-wm?

If you load the wm.mgz over the lh.orig.nofix, then in the orig.nofix load the file defect_labels as an overlay and change the overlay settings to that the min is 1 and click the "use overlay color" button it will show you the regions of the surface that are defective. You will then need to edit the wm.mgz to remove the handle/hole that is the defect. cheers Bruce On Fri, 26 May 2017, Hibert, Matthew Louis wrote: > Hi All, > I reconstructed 20 subjects with a 750um isotropic MPRAGE collected at 7T > and while most look good, 4 of the subjects have a similar section of the > left STG removed from the final surfaces (picture attached).
