mdtraj.open¶

mdtraj.open(filename, mode='r', force_overwrite=True, **kwargs)¶

Open a trajectory file-like object

This factor function returns an instance of an open file-like object capable of reading/writing the trajectory (depending on ‘mode’). It does not actually load the trajectory from disk or write anything.

Parameters:

filename : str

Path to the trajectory file on disk

mode : {‘r’, ‘w’}

The mode in which to open the file, either ‘r’ for read or ‘w’ for write.

force_overwrite : bool

If opened in write mode, and a file by the name of filename already exists on disk, should we overwrite it?

Returns:

fileobject : object

Open trajectory file, whose type is determined by the filename extension

Other Parameters:

kwargs : dict

Other keyword parameters are passed directly to the file object
