It is my implementation of the spm_coreg program written by John Ashburner using normalized mutual information. I liked the spm program so much that I put the effort into replicating its behavior in C. My guess is that BBR was failing because the initialization was failing. Still I like mri_coreg for PET data because the blurriness can throw BBR off a bit. What kind of PET data do you have?

Hi Doug,
I just want to say that mri_coreg worked tremendously well for the registration of some very blurry PET-PK data. I was not getting any success with bbregister and init-fsl or mri_robust_register options.
How does this technique differ from the boundary-based registration?
Thanks a lot.
Best Wishes, Elijah
