Open Babel is software to convert and manipulate chemical data files. It is an open, collaborative project allowing anyone to search, convert, analyze, or store data from molecular modeling, chemistry, biochemistry, or related areas.
Open Babel is a free, open-source version of the Babel chemistry file translation program. Open Babel is a project designed to pick up where Babel left off, as a cross-platform program and library designed to interconvert between many file formats used in molecular modeling, computational chemistry, and many related areas.
The command-line interface is mostly identical to the old ‘babel’ executable and recognizes these file formats among many others: Alchemy, ChemDraw, CML, GAMESS, Gaussian, HyperChem, MDL Isis and Molfile, MOPAC, MPQC, PDB, SMILES and XYZ.
Features include:
- Ready-to-use programs for converting files, molecular searching, chiral detection, and superimposing molecules.
- Support for a huge variety of common chemical file formats, including SDF/MOL, Sybyl mol2, PDB, SMILES, XYZ, CML, ABINIT, XCrySDen XSF…
- Automatic recognition of file type based on filename extension.
- Batch conversion for multiple molecules in one file (e.g., splitting, merging, batch operation).
- Gasteiger-Marsili partial charge calculation.
- Support for Molecular Mechanics.
- Hydrogen addition and deletion.
- Isotope support, calculation of average and exact masses.
- Flexible atom typer and perception of multiple bonds from atomic coordinates.
- Automatic feature perception (rings, bonds, hybridization, aromaticity).
- Read, write and convert over 110 chemical file formats.
- Filter and search molecular files using SMARTS and other methods.
- Supports molecular modeling, cheminformatics, bioinformatics, organic chemistry, inorganic chemistry, solid-state materials, nuclear chemistry.
