How to predict antibody sequence for antigen with cyclic feature?

Hi, 
Thank you sooo much for your wonderful work, it is soooo helpful and amazing!!!
It reminds me whether we can predict the antibody sequence for our own antigens with special structures, just like cyclic peptide? And if so, how can we set the parameters for such Ag sequence? If not, could you please give me some other tips?
Looking forward to your reply!
Thanks again and best regards.
