The electronic Ligand Builder and Optimisation Workbench (eLBOW) is a program module of the PHENIX suite of computational crystallographic software. It's designed to be a flexible procedure using simple and fast quantum chemical techniques to provide chemically accurate information for novel and known ligands alike. A variety of input formats and options allow for the attainment of a number of diverse goals including geometry optimisation and generation of restraints.
