Open Babel 3.1                                    Oct 10, 2019                                          obgen(1)

       The  obgen  tool will generate 3D coordinates for molecules in a file (e.g. multi-molecule SMILES files).
       The resulting structure will be optimized using the given forcefield and checked  for  the  lowest-energy
       conformer using a Monte Carlo search.  Output will be sent to standard output in the SDF file format.

       View the possible options, including available forcefields:
             obgen

       Generate 3D coordinates for the molecule(s) in file test.smi:
             obgentest.smi

       Generate 3D coordinates for the molecule(s) in file test.smi using the UFF forcefield:
             obgen-ffUFFtest.smi

       If no filename is given, obgen will give all options including the available forcefields.
