The wm.mgz is expected since we added denoising to it; but it does not

brainmask.mgz is created from T1.mgz. The T1.mgz will be affected by
control points, but only if you run it from the beginning. The surfaces

Hello, our lab has been using freesurfer for years, dating back to version 4.3
and recently ran into a problem with a new installation of 7.2. After adding
control points in the typical fashion and saving them into the subject’s tmp

The control points mark voxels as belonging to white matter, and should
be marked sparingly. They are not points on a spline, as it appears you

Hi Ri,
you have to be careful to only put the control points in voxels that are
completely white matter (no partial voluming). I also don't know what you
mean by the control points didnt get converted to a continuous line. Can

cheers,
