Yes, thanks Bruce
I'd checked the intensity values, and they were exactly the same as before the skull stripping

Hi Gabriel
the contrast probably isn't changed, just the display. Tkmedit tries to
compute good window level settings based on the image content, and after
stripping there will be far less bright fat, so the brain will probably
look brighter. Check the actual voxel values.
cheers
Bruce
