Load a TINKER .arc file from disk.

Parameters:

filename : str

String filename of TINKER .arc file.

top : {str, Trajectory, Topology}

The .arc format does not contain topology information. Pass in either the path to a pdb file, a trajectory, or a topology to supply this information.

stride : int, default=None

Only read every stride-th frame

atom_indices : array_like, optional
