obgen: generate 3D coordinates for a molecule

NAME

obgen - generate 3D coordinates for a molecule

SYNOPSIS

[OPTIONS ] filename

DESCRIPTION

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.

OPTIONS

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

-ff forcefield
Select the forcefield

EXAMPLES

View the possible options, including available forcefields:

"obgen"

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

"obgen test.smi"

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

"obgen -ff UFF test.smi"
