Latest version 1.8.0 (March 1 2021)
Balloon creates 3D atomic coordinates from molecular connectivity via distance geometry and confomer ensembles using a multi-objective genetic algorithm. The input can be SMILES, SDF or MOL2 format. Output is SDF or MOL2. Flexibility of aliphatic rings and stereochemistry about double bonds and tetrahedral chiral atoms is handled.
The software has been ported to Linux, Mac OS X, and Microsoft Windows platforms.
