Hi!

I am having some issue at the interface between mri_nu_correct.mni and mri_normalize, using v5.3.

Specifically, the output when applying mri_nu_correct to a T1 is quite dark, with white matter in the range of 15. Contrast is ok. When I apply mri_normalize to nu, it does not scale the data to white matter 110. This happens with and without a brain mask, and with various other parameter choices.

I am tempted to just add 100 to all voxels.

Any advice?

Thank you,

Caspar
