OpenBabelGUI is an open, collaborative project allowing anyone to convert, analyze, search or store datafrom molecular modeling, chemistry, biochemistry, or related areas.What's new in OpenBabelGUI : New support for 3D coordinate generation using the OBBuilder class.Note that this code directly supports non-chiral compoundsStereochemistry may or may not be supported in this releaseSignificantly faster force fields (up to 200x faster) and support for constrained optimization.New force fields, including complete UFF, MMFF94, and MMFF94s implementations.Monte Carlo conformer search support, including a new obconformer tool.Unified framework for plugin classes, including easy-to program file formats, descriptors, filters, force fields, fingerprints, etc.A new "descriptor" plugin framework for QSAR descriptors, etc.Initial descriptors include hydrogen-bond donors, acceptors, octanol/water partition, topological polar surface area, molar refractivity, molecular weight, InChI, SMARTS, titles, Lipinski Rule of Five, etc.A new "filter" plugin framework for selecting molecules by title, molecular weight, etc.Facility to add new "ops", commandline options or operations o...
