OEReceptorSetCustomConstraints
OEReceptorSetCustomConstraints(rec: Union[OEGraphMol,OEMol,OEQMol],
arg2: OECustomConstraints) -> bool
Sets the receptor’s custom constraints (copied from customConstraints).
Returns true if successful.
It is only valid to call this function if receptor is a valid receptor
(i.e., OEIsReceptor returns true).
