The wm.mgz is expected since we added denoising to it; but it does not
matter because wm.mgz is essentially a binary mask of WM. The
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

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
