Enter an input value, for example a SMILES like "CCCC" Select the "Input format", for example "smi" Select an output format, for example "mol" Click on "Convert" An SDF property, as the identifier ROTATABLE_BOND could be. One challenge, if you're not from a chemistry background, is to know that for most molecules, there are many energetically-accessible conformers (e. The “EXYZ” chemical file format is an extended version of the standard “XYZ” chemical file format with additional keywords and informations about the unit cell and virtual atoms. I read each xyz file and turn it into a pybel molecule. This format allows you to filter molecules from multimolecule files without the risk of losing any additional information they contain, since no format conversion is carried out. babel infile. babel *.
