 the structure of an antibody-antigen complex using knowledge of the hypervariable loops
 on the antibody (i.e., the most basic knowledge) and epitope information identified from NMR experiments for the antigen to guide the docking.

 An antibody is a large protein that generally works by attaching itself to an antigen,
 which is a unique site of the pathogen. The binding harnesses the immune system to directly
 attack and destroy the pathogen. Antibodies can be highly specific while showing low immunogenicity (i.e. the ability to provoke an immune response),
