mdtraj.formats.AmberRestartFile

class mdtraj.formats.AmberRestartFile(filename, mode='r', force_overwrite=True)

Interface for reading and writing AMBER ASCII restart files. This is a file-like object, that supports both reading and writing depending on the mode flag. It implements the context manager protocol, so you can also use it with the python ‘with’ statement.

Parameters

filenamestr

The name of the file to open

mode{‘r’, ‘w’}, default=’r’

The mode in which to open the file. Valid options are ‘r’ or ‘w’ for ‘read’ or ‘write’

force_overwritebool, default=False

In write mode, if a file named filename already exists, clobber it and overwrite it
