Hi AFNI Experts,

I had a few questions about Epi to Anatomical Alignment, specifically regarding boundary-based registration. I am interested in this approach because I am looking for ways to improve my anat-epi coregistration. I ran into the BBR method (Greve & Fischl, 2009), but lack context on its general use:

Does AFNI implement the BBR algorithm? Is this the -edge switch on align_epi_anat?

The BBR method is treated as an "improved EPI to structural registration" in FSL, but the -edge option does not appear in any of AFNI's recommended processing pipelines. What are your thoughts on efficacy / general application of this approach? (I know there is no "right" answer, but if anyone has any informed opinions or referred articles, I would love to hear).

Thanks very much,

Andrew
