Description:
 def read_pybel(value, name=None):
 """ Create an `Atoms` object from content parsed by Pybel. `Pybel <https://openbabel.org/docs/dev/UseTheLibrary/Python_Pybel.html>`_ is a Python module that simplifies access to the OpenBabel API, a chemical toolbox designed to speak the many languages of chemical data. It’s an open, collaborative project allowing anyone to search, convert, analyze, or store data from molecular modeling, chemistry, solid-state materials, biochemistry, and related areas. Parameters value : `str`, `pybel.Molecule`, `openbabel.OBMol` A path to a file, or either a Pybel Molecule object, or OpenBabel OBMol. name : `str`, optional Name for chemical species. If not given, this is set to the file path, if known. Chemical equations mention this name when refering to the returned object. Returns ------- molecule : `Atoms` All attributes convertible from Pybel to cclib are made available as attributes in the returned object. Notes ----- The following attributes are converted from Pybel to cclib: `atomcoords`, `atommasses`, `atomnos`, `natom`, `charge` and `mult`. One must keep in mind that `charge` and `mult` are not always reliable, since these are often calculated from atomic formal charges. Examples -------- array([6, 6, 6, 6, 7, 1, 1, 1, 1, 1], dtype=int32) 10 0 """
