...It is capable of dealing with plotting, electronic structure calculation and multicomponent calculations. Current version reads XYZ and deMon output files. Displays image of geometry, atomic orbitals, molecular orbitals, density and Fukui functions in a few different formats. In situ SCF Hartree-Fock calculations available.

Scalable Molecular Analysis Solver for High-performance computing systems (SMASH) is massively parallel software for quantum chemistry calculations and released under the Apache 2.0 open source license. It is currently capable of energy, analytical gradient, and geometry optimization calculations of Hartree-Fock theory and Density Functional Theory (DFT), and energy calculations of Second-order Moller-Plesset (MP2) perturbation theory. DFT calculations can be performed on 100,000 CPU cores with high parallel efficiency.

Gabedit is a Graphical User Interface for FireFly (PC-Gamess), Gamess-US, Gaussian, Molcas, Molpro, MPQC, NWChem, OpenMopac, Orca, PSI4 and Q-Chem computational chemistry packages.

QMForge reads output from various quantum mechanical calculations and provides tools for analyzing these results. Specifically, population (Mulliken and C-squared), fragment, and charge decomposition analyses are available. See https://qmforge.net for more info.

...New project page: https://github.com/yesint/pteros New documentation page: https://yesint.github.io/pteros/ Pteros is the C++ library for custom molecular modeling and simulations codes designed for researchers, not for C++ gurus. Provides facilities for PDB, XTC and TRR files IO, powerful selections, geometry transformations, RMSD fitting and alignment, etc.

LATEST VERSION NOW LOCATED AT http://git.durrantlab.com/jdurrant/lipidwrapper As ever larger and more complex biological systems are modeled in silico, approximating physiological lipid bilayers with simple planar models becomes increasingly unrealistic. When building large-scale models of whole subcellular environments, models of lipid membranes with carefully considered, biologically relevant curvature are essential. LipidWrapper, written by Jacob Durrant in the lab of Rommie E. Amaro,...

A GUI program written in Perl and utilizing Tk that is meant to solve equations commonly found in math and science. Current equation set is based upon High School Geometry, Algebra II, Trigonometry, and Chemistry with more to come.

GVIB is a user friendly package for vibrational analysis. Given a molecular geometry, it will calculate vibrational frequencies and intensities using anharmonic internuclear potential.
