Normalization (-<no>normalization)
Performs intensity normalization of the orig volume and places the result in mri/T1.mgz. Attempts to correct for fluctuations in intensity that would otherwise make intensity-based segmentation much more difficult. Intensities for all voxels are scaled so that the mean intensity of the white matter is 110. If there are problems with the normalization, users can add control points. See also normalization2.
