[Freesurfer] question 2 about using control points

Hi Folks,

We noticed that some WM was left out from the yellow surface.

But when we look at wm.mgz these values of these voxels are in the range 80-95 (shown in the figure) In such cases should we remove these voxels from wm.mgz (using the right click option) and then include them again ? That is, this would change the voxel values from 80-95 to 255..

I ask this because sometimes, we see that the yellow surface is clipped but there is nothing to include in the wm.mgz since the corresponding voxels do have some intensity values in the range 75-90.

Please let me know if you need more information/clarification about this question.

thanks Mehul
