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?
