Hi Pietro, I think you should try redoing the control points from scratch, but with fewer control points and sparser placement. Currently you have 198 control points tightly packed in only a couple regions. Furthermore, there is one control point at 128, 128, 128 which is right in the thalamus which should not be there, maybe an accidental click?
Take a look at the placement of the control points in the snapshots on this tutorial page: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/ControlPoints_freeview
If you compare the norm.mgz volumes before/after editing, you will notice the extreme hyper-intense wm (130+) in the temporal lobes after adding control points and rerunning. The norm.mgz is passed to mri_pretess to create the wm.mgz. You can see there is overlap between the hyper-intense voxels on the norm and the voxels not being included in the wm mask, which leads to major errors in the wm surface. -Louis
