QXRD is software for the acquisition and analysis of X-ray data taken with 2 dimensional detectors. The software can drive a Perkin Elmer XRD series flat panel detector and can be remote-controlled via a socket interface, or directly from SPEC

OSRA is a utility designed to convert graphical representations of chemical structures and reactions, as they appear in journal articles, patent documents, textbooks, trade magazines etc., into SMILES or SD file format- a computer recognizable molecular structure You can find links to the binary executables here: https://sourceforge.net/p/osra/wiki/Download/

Software and codes created in "Laboratorio de Química Computacional" of "Facultad de Ciencias y Tecnología" of "Universidad de Carabobo"

MESMER is designed to analyze and simulate reactions in the gas phase that take place on a potential energy surface that is characterized by having one or more potential wells, and which are typically described by rate coefficients that depend on pressure (or concentration) as well as temperature. MESMER allows you to simulate systems over a wide range of pressures and temperatures, extract rate coefficients, analyze experimental data, fit model parameters and represent rate coefficients in formats that can be used directly in large scale simulations (e.g. Cantera or Chemkin).

QuteMol is a real time, high quality molecular visualizer that offers an array of innovative visual effects. QuteMol aims at improving the clarity of rendered images and at offering a better understanding of the molecular 3D shape and spatial structure.

The Sashimi project hosts the Trans-Proteomic Pipeline (TPP), a mature suite of tools for mass-spec (MS, MS/MS) based proteomics: statistical validation, quantitation, visualization, and converters from raw MS data to the open mzML/mzXML formats.

Cantera is a suite of object-oriented software tools for problems involving chemical kinetics, thermodynamics, and/or transport processes. It can be used from MATLAB, Python, C++, or Fortran.

ShelXle combines an editor with syntax highlighting for the SHELXL-associated .ins (input) and .res (output) files with an interactive graphical display for visualization of a three-dimensional structure including the electron density (Fo) and difference density (Fo-Fc) maps. See J. Appl. Cryst. (2011). 44, 1281–1284. for details.

Open source steam property routines in C. Implements the IAPWS-IF97 steam tables from the International Association for the Properties of Water and Steam. Includes two-way property solvers and test suite. Can be used from C/C++, Fortran, Python, LabVIEW, Octave and ASCEND.

Fast and efficient 3D pharmacophore search developed by the Camacho Lab (http://smoothdock.ccbb.pitt.edu) at the University of Pittsburgh. Source code is available through the svn repository.

Object-oriented crystallographic library and program, for the analysis of Crystal structures from scattering experiments: optimized scattering computation, Graphical interface for structures and data, global optimization algorithms.

EChem++ is a software system based on an object oriented approach to electrochemical experimentation, simulation, and data analysis. Currently, development emphasis lies on the modelling and simulation as well as the analysis modules.

PyMOlyze is a graphical program to analyze the results of quantum chemistry (HF/DFT) calculations. Features include various population analyses, fragment analysis, monitoring structures during an optimization, and a simple, but powerful, XYZ editor.

Clip is an interactive program for simulation, indexing and refinement of Laue diffraction images.

ED Software project contains several programs used (mostly) for processing gas-phase electron diffraction (GED) experimental data.

Charmol is a cross-platform GUI/command-line based program for making high-quality pictures of molecular structures, nowadays working on Linux, MacOS and Windows. As output, it produces POV-Ray rendered images or files in VRML format. Charmol is capable of making pictures containing: - from small- to large-size molecules - more molecules together (different settings possible) - orbitals using molden and fchk files (GTO functions up to 'h' angular momentum supported) - surfaces using gaussian cube files (also color-mapped surfaces according to potential) - schematic representation of vibrations using arrows - user-defined arrows representing vectorial properties - measuring gauges - combinations of these features (more orbitals together, orbitals and arrows together etc.) Charmol allows for fine tuning of the final molecular design.

The Massively Parallel Quantum Chemistry program, MPQC, computes properties of atoms and molecules from first principles using the time independent Schrödinger equation.

OpenGrowth is a research program which grows new ligands in proteins by connecting small organic fragments. The details can be found in the original publication "OpenGrowth: an automated and rational algorithm for finding new protein ligands" (J. Med. Chem., http://dx.doi.org/10.1021/acs.jmedchem.5b00886). To use OpenGrowth, you will need OpenGrowth_1.0.zip and Resources_1.0.2.zip that can be found by clicking on the Files menu in the horizontal bar at the top (https://sourceforge.net/projects/opengrowth/files). OpenGrowthGUI, FOG2.0, and the 3Mer-Screen stand-alone can be found in OpenGrowth_1.0.zip. To prepare new fragments you need BuildingFragments_1.0.1.zip and the scripts for MD simulations are in MD-Scripts_1.0.1.zip. SMoG2016.tar.gz allows to compute a score with the newly developed function (J. Chem. Inf. Mod., http://pubs.acs.org/doi/abs/10.1021/acs.jcim.6b00610). For any questions, please send emails exclusively at opengrowth-discuss@lists.sourceforge.net.

The repository has been moved to: https://github.com/wojdyr/fityk. Fityk is nonlinear curve-fitting and data analysis software. It is specialized in fitting peaks (bell-shaped functions like Gaussian, Loretzian, Pearson7, Voigt) to experimental data.
