SymmDock is an algorithm for prediction of complexes with C_n symmetry by geometry based docking. Given the structure of the asymmetric unit of the multimer complex, SymmDock predicts the structure of the entire complex. A C_n symmetry type complex is a complex with a rotational symmetry of order n about a symmetry axis. The rotation angle alpha is of 360/n degrees.

The input to the method is a 3D coordinate set of the asymmetric unit molecule and a number. The number n stands for the desired number of asymmetric units in the output complex. The output of the method is a list of complexes, that fulfill the cyclic symmetry constraints.
