Hi,
I also have the bbr registration problem. In order to better do registration between DTI and anatomical images. I added cost -bbr to the command line instead of using the default registration cost function. And I got ERROR::set_bbr_seg: could not find any boundary points! WARNING:: Found NaN in BBR cost (2). I checked that there is no NAN in ref and in matrix. Have any other people met similar problems? I would be very grateful if I could got some help from you.
Thank you and best regards,
Yixin
