should be easy enough to do in matlab. Just load the wm volume, then find
all the T1 voxels that are nonzero in it.

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
