What is openbabel

openbabel is:

Open Babel is a chemical toolbox designed to speak the many languages of chemical data. It allows one to search, convert, analyze, or store data from molecular modeling, chemistry, solid-state materials, biochemistry, or related areas. Features include:

  • Hydrogen addition and deletion
  • Support for Molecular Mechanics
  • Support for SMARTS molecular matching syntax
  • Automatic feature perception (rings, bonds, hybridization, aromaticity)
  • Flexible atom typer and perception of multiple bonds from atomic coordinates
  • Gasteiger-Marsili partial charge calculation

File formats Open Babel supports include PDB, XYZ, CIF, CML, SMILES, MDL Molfile, ChemDraw, Gaussian, GAMESS, MOPAC and MPQC.

This package includes the following utilities:

  • obabel: Convert between various chemical file formats
  • obenergy: Calculate the energy for a molecule
  • obminimize: Optimize the geometry, minimize the energy for a molecule
  • obgrep: Molecular search program using SMARTS pattern
  • obgen: Generate 3D coordinates for a molecule
  • obprop: Print standard molecular properties
  • obfit: Superimpose two molecules based on a pattern
  • obrotamer: Generate conformer/rotamer coordinates
  • obconformer: Generate low-energy conformers
  • obchiral: Print molecular chirality information
  • obrotate: Rotate dihedral angle of molecules in batch mode
  • obprobe: Create electrostatic probe grid
