Is it possible to obtain and intensity histogram of the wm voxels, or descriptive stats (eg., Mean, SD) as a quick check?

if it succeeds then the intensity in the wm should be exactly 110 over much of the brain, and 90<wm<120 pretty much everywhere

Hi
What is a typical example of when the intensity normalization process
fails?
Does the over-all image seem brighter? What is a good indicator of
success
or failure?
Thanks, Tracy
