Hi Martin,

you only need to do it if there is a connection from mis-segmented eye muscle as wm to the body of the wm.

Hi,

I have a question about using tkmedit. Up until now, our group has been editing out the eye muscles after autorecon-1 and editing out the optic nerve after autorecon-2. I know on earlier versions of freesurfer it was highly recommended to do so because the program would sometimes crash otherwise. However, using the newer version, the program seems to know to not include eye muscles in the pial matter boundary, and the optic nerve does create a region of high curvature at that point, but it doesn't crash the program.

I was wondering, in your own analyses, did you do editing at each step (excluding situations that are obviously out of the norm), and would it be a bad thing not to edit those regions in the majority of cases?

Thanks, Martin Chang
