In this work, we discuss an open source implementation of a new fragment-based approach for coordinate generation in Open Babel, with improved accuracy and performance. We compare the stereochemical accuracy with the previous implementation and the open source RDKit distance geometry method, as well as speed and geometric accuracy, measured by heavy-atom root mean square displacement with experimental crystal structures (RMSD), bond distance, bond angle, and torsional/dihedral angle errors. RDKit is chosen as a baseline because it is widely used and a benchmark paper describes it as "competitive with the commercial algorithms". We also discuss molecules with large geometric or stereochemical errors and future work to improve both geometric and stereochemical accuracy while retaining fast performance.
