Hi Elissa

the control point can still have an effect if the brainmask.mgz intensity is not 110. Please make sure that you aren't adding control points to gray matter though - that will mess everything up!

Hello freesurfer experts,

I have a question. I think some of the gray matter is being underestimated and some white matter isn't being classified in particular areas. I went to add control points and I noticed that sometimes the places I want to put control points in have voxels there in the wm.mgz mask. What does it mean when this happens? Should I still add control points or leave it alone? I've attached an example.

Thank you!
