^a Antigen-antibody complexes from protein docking benchmark 2.0. ^b 17 recently released antigen-antibody complex structures in PDB. Unbound structures of both databsets were used for prediction and bound structures were used for identification of interface residues. The AUC values were calculated and averaged for all the proteins in two datasets, respectively.
