GalaxyTongDock performs symmetric and asymmetric protein-protein docking. Use GalaxyTongDock_A for asymmetric docking of two different proteins, GalaxyTongDock_C for symmetric docking of an oligomer protein with Cn symmetry, and GalaxyTongDock_D for symmetric docking of an oligomer protein with Dn symmetry. GalaxyTongDock_A may be preferred to GalaxyHeteromer for hetero-diemric structure prediction if experimental structures for similar portein complexes do not exist but some information on binding interface residues or on residues that should not be in the interface is available. GalaxyTongDock_C,D may be preferred to GalaxyHomomer for homo-oligomer structure prediction if experimental structures for similar portein complexes do not exist but some information on binding interface residues or on residues that should not be in the interface is available.
