Hi, I have been trying to make freesurfer include all of my white matter in the wm-surface. It seems to run directly across some of the gyri in my brain volume (see attached picture). I first tried to add control points at the base of the gyri, and then along the gyri, but that did not seem to have much effect. Then I manually drew the white matter onto the wm.mgz-volume (see attached picture), but that did only help for some of my gyri. Do you have any tips on how to force freesurfer to include the remaining white matter in the wm surface?
Thanks, Martin Ystad
