OEGetCrystalSymmetry¶

bool OEGetCrystalSymmetry(OECrystalSymmetryParams &params,
                          const OEChem::OEMolBase &mol)

Retrieves the crystal symmetry information from the molecule. The retrieved information is stored in the given OECrystalSymmetryParams object.

Note

Use this overloaded function in the supported wrapped languages: Python, Java and C#.

Example:

p = oechem.OECrystalSymmetryParams()
if oechem.OEGetCrystalSymmetry(p, mol):
    print("a= %f b= %f c= %f" % (p.GetA(), p.GetB(), p.GetC()), end=" ")
    print("alpha= %f beta= %f gamma= %f" % (p.GetAlpha(), p.GetBeta(), p.GetGamma()), end=" ")
    print("spacegroup= %d z-value= %d" % (p.GetSpaceGroup(), p.GetZValue()))

bool OEGetCrystalSymmetry(const OEChem::OEMolBase &mol, float &a, float &b, float &c,
                          float &alpha, float &beta, float &gamma,
                          unsigned int &sgnumber)

bool OEGetCrystalSymmetry(const OEChem::OEMolBase &mol, float &a, float &b, float &c,

                          unsigned int &sgnumber, unsigned int &zvalue)

Retrieves the following the crystal symmetry information from the molecule:

standard cell lengths
cell angles ‘alpha’, ‘beta’ and ‘gamma’ and
spacegroup number
z-value
