Molsketch is a 2D molecular editing tool. Its goal is to help you draw molecules quick and easily. Of course you're creation can be exported afterwards in high quality in a number of vector and bitmap formats.

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).

RasTop is a molecular graphics program intended for the visualisation of proteins, nucleic acids and small molecules based on the popular Rasmol software. The program is aimed at the rapid visualization and analysis of molecules.

EXTREMA is an interactive program with publication quality graphics and mathematical analysis capabilities. EXTREMA can be GUI and/or command driven. The command language includes conditional branching, looping and subroutine calling constructs.

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.

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.

qmol is a simple molecular weight calculator, available for Linux and Windows, derived from Tomislav Gountchev's KMol. You can enter a formula, (e.g. CH3(CH2)2OH) and get its molecular weight (60.0959 g/mol) and its elemental composition (C3H8O: C 59.96; H 13.42; O 26.62 %). See the features list below for more details or consult the wiki page: https://sourceforge.net/p/qmol/wiki/Home/. For Windows binary and source code see the files section: https://sourceforge.net/projects/qmol/files/ Binary packages (rpm/deb) for openSUSE Leap 15.2-42.2, xUbuntu 20.10-19.10, 17.04, Fedora 33, CentOS 8, Scientific Linux 7, and Debian 10.0-8.0 can be found at: http://download.opensuse.org/repositories/home:/lineinthesand/

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

trj_cavity finds protein cavities throughout Molecular Dynamics (MD) simulation trajectories. The program works with files in PDB format, but it also can read/generate GROMACS compatible formats such as XTC. The same project can be compiled as a GROMACS tool or as a standalone version. Installation instructions are provided in the INSTALL file of the project and in https://sourceforge.net/p/trjcavity/wiki/Home/#ffad If you need support using this tool (or report bugs), please post it in the discussion forum. Remarks: v2 runs in parallel and supports GROMACS v5.1+ series. If you want to continue on using GROMACS v4.x, please use trj_cavity_v1.1.
