Freesurfer Folks,
I am having trouble with a handful of subjects in which there are portions of white and grey matter not included by the white and pial surfaces. The problems at hand seemed like good candidates for control points, so I added some and have run recon2-cp on these subjects (in FreeSurfer v 4.0.1). I am having limited success fixing the problems, especially in the temporal lobes, and have attached a couple screen caps of one of the more egregious problems. Most of the voxels I believe to be white matter are in the 100-110 range of intensity. If it can be guessed at from these screen shots, is there some principle of using control points that I am not getting right? Also, would editing the wm.mgz file be another possible avenue of fixing the problem? As always, thanks in advance.
