Hi Jared
use bbregister as usual then you can use mri_convert with -ait to apply the inverse transform.

Hi,
Is there a way to use bbregister to register a FreeSurfer image (e.g., rawavg.mgz) to a diffusion image from the same participant? In other words, is there a way to specify --mov rawavg.mgz and make the target (template) image a b0 diffusion image? Or at least to perform an inverse transform on the rawavg image after registering the b0 to the rawavg?
I plan on trying mris_cvs_register but I was wondering if bbregister can do what I want.
I've used flirt, fnirt, and SyN registration methods but flirt isn't quite accurate enough for intra-subject, multi-modal registration, fnirt is better but still has troubles with cortical regions, and SyN has been too variable with results.
Thank you,
