It implements the context manager protocol,\n    so you can also use it with the python 'with' statement.\n\n    The conventional units in the BINPOS file are angstroms. The format only\n    supports storing the cartesian coordinates.\n\n    Parameters\n    ----------\n    filename : str\n        The filename to open. A path to a file on disk.\n    mode : {'r', 'w'}\n        The mode in which to open the file, either 'r' for read or 'w' for write.\n    force_overwrite : bool\n        If opened in write mode, and a file by the name of `filename` already\n        exists on disk, should we overwrite it?\n\n    Other Parameters\n    ----------------\n    min_chunk_size : int, default=100\n        BINPOS, In read mode, we need to allocate a buffer in which to store the data\n        without knowing how many frames are in the file. This parameter is the\n        minimum size of the buffer to allocate.\n    chunk_size_multiplier : int, default=1.5\n        In read mode, we need to allocate a buffer in which to store the data\n        without knowing how many frames are in the file. We can *guess* this\n        information based on the size of the file on disk, but it's not perfect.\n        This parameter inflates the guess by a multiplicative factor.\n\n    Examples\n    --------\n    >>> # copy data from one file to another\n    >>> with BINPOSTrajectoryFile('traj.binpos') as f:\n    >>>     xyz = f.read()\n    >>> with BINPOSTrajectoryFile('out.binpos') as f:\n    >>>    f.write(xyz)\n\n    See Also\n    --------\n    mdtraj.load_binpos : High-level wrapper that returns a ``md.Trajectory``\n    "), /*tp_doc*/
