 """ Create an `Atoms` object from data attributes parsed by cclib. `cclib <https://cclib.github.io/>`_ is an open source library, written in Python, for parsing and interpreting the results (logfiles) of computational chemistry packages. Parameters value : `str`, `cclib.parser.logfileparser.Logfile`, `cclib.parser.data.ccData` A path to a logfile, or either a cclib job object (i.e., from `cclib.ccopen`), or cclib data object (i.e., from ``job.parse()``). name : `str`, optional Name for chemical species. If not given, this is set to the logfile path, if known. Chemical equations mention this name when refering to the returned object. Returns ------- molecule : `Atoms` All attributes obtainable by cclib are made available as attributes in the returned object. Examples -------- array([6, 6, 6, 6, 7, 1, 1, 1, 1, 1], dtype=int32) 0 """
