obgen — generate 3D coordinates for a molecule
|obgen|| [ |
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.
If no filename is given, obgen will give all options including the available forcefields.
