Openmm metadynamics example
WebTwo Metadynamics examples are included in the Examples/User/Meta directory. In the first example, Metadynamics is used to sample the free energy surface of a two-dimensional particle undergoing Langevin dynamics. This example is found in the Single_Atom directory and uses LAMMPS. The files included are described below: WebLet's use one of the OpenMM reporters that mdtraj provides. This is the hdf5 reporter, which saves all kinds of information, including the topology, positions, energies, etc to disk. To …
