A script for automated 3-dimentional structure generation and conformer search from 2- dimentional chemical drawing.

ABSTRACT: Building 3-dimensional (3D) molecules is the starting point in molecular modeling. Conformer search and identification of a global energy minimum structure are often performed computationally during spectral analysis of data from NMR, IR, and VCD or during rational drug design through ligand-based, structure-based, and QSAR approaches. I herein report a convenient script that allows for automated building of 3D structures and conformer searching from 2-dimensional (2D) drawing of chemical structures. With this Bash shell script, which runs on Mac OS X and the Linux platform, the tasks are consecutively and iteratively executed without a 3D molecule builder via the command line interface of the free (academic) software OpenBabel, Balloon, and MOPAC2012. A large number of 2D chemical drawing
