Hi Victor
the best way to remove intensity inhomogeneities is with control points usually. The wm.mgz gives us an initial estimate of the surface locations, but we then deform it based on the intensities in the brain.mgz volume. So if it looks like wm extends that far out in the brain your wm.mgz edits are unliekly to fix things

Hi Freesurfer developers,
I have a subsample of a FS dataset that have scanner-originated hyperintensities in the bilateral supramarginal/temporal lobes. I've manually removed these hyperintensities by editing the wm.mgz, yet FS seems to be unable to recognize these edits when looking at the ?h.white and aparc+aseg.mgz. Is there a possible way to rectify these errors?
I am using FS6 for linux
Here are some pictures:
