openforcefield.utils.structure.save_system_to_amber(openmm_topology, system, positions, prmtop, inpcrd)[source]¶

Save an OpenMM System, with provided topology and positions, to AMBER prmtop and coordinate files.

Parameters:

Parameters:	openmm_topology : OpenMM Topology Topology of the system to be saved, perhaps as loaded from a PDB file or similar. system : OpenMM System Parameterized System to be saved, containing components represented by Topology positions : unit.Quantity position array Position array containing positions of atoms in topology/system prmtop : filename AMBER parameter file name to write inpcrd : filename AMBER coordinate file name (ASCII crd format) to write
