Description:
 def from_magnetic_spacegroup( cls, msg, lattice, species, coords, site_properties, transform_setting=None, coords_are_cartesian=False, tol=1e-5):
 """ Generate a structure using a magnetic spacegroup. Note that only symmetrically distinct species, coords and magmoms should be provided.] All equivalent sites are generated from the spacegroup operations. Args: msg (str/list/:class:`pymatgen.symmetry.maggroups.MagneticSpaceGroup`):
 The magnetic spacegroup. If a string, it will be interpreted as one of the notations supported by MagneticSymmetryGroup, e.g., "R-3'c" or "Fm'-3'm". If a list of two ints, it will be interpreted as the number of the spacegroup in its Belov, Neronova and Smirnova (BNS) setting. lattice (Lattice/3x3 array):
 The lattice, either as a :class:`pymatgen.core.lattice.Lattice` or simply as any 2D array. Each row should correspond to a lattice vector. E.g., [[10,0,0], [20,10,0], [0,0,30]] specifies a lattice with lattice vectors [10,0,0], [20,10,0] and [0,0,30]. Note that no attempt is made to check that the lattice is compatible with the spacegroup specified. This may be introduced in a future version. species ([Specie]):
 Sequence of species on each site. Can take in flexible input, including: i. A sequence of element / specie specified either as string ii. List of dict of elements/species and occupancies, e.g., disordered structures. coords (Nx3 array):
 list of fractional/cartesian coordinates of each species. site_properties (dict):
 Properties associated with the sites as a dict of sequences, e.g., {"magmom":[5,5,5,5]}. The sequences have to be the same length as the atomic species and fractional_coords. Unlike Structure.from_spacegroup(), this argument is mandatory, since magnetic moment information has to be included. Note that the *direction* of the supplied magnetic moment relative to the crystal is important, even if the resulting structure is used for collinear calculations. coords_are_cartesian (bool):
 Set to True if you are providing coordinates in cartesian coordinates. Defaults to False. tol (float):
 A fractional tolerance to deal with numerical precision issues in determining if orbits are the same. """
