GAMGI: GAMGI (General Atomistic Modelling Graphic Interface) is a program to build, view, and analyze atomic strucures such as molecules, crystals, glasses, liquids, etc. It aims to be useful for: the scientific community working in Atomistic Modelling that needs a graphic interface to build input data and to view and analyse output data, calculated with Ab-Initio and Molecular Mechanics programs; the scientific community at large studying chemistry, physics, materials science, geology, etc., that needs a graphic interface to view and analyse atomic structural information and to prepare images for presentations in classes and seminars; teaching chemistry and physics in secondary schools and universities; science promotion in schools, exhibitions and science museums.

GDIS: "GDIS' is a GTK/OpenGL based program for displaying isolated molecules, periodic systems, and crystalline habits. It also acts as a GUI to packages such as GAMESS, GULP, and POVRay to provide energy minimizations and publication quality rendering.

GElemental: gElemental is a periodic table viewer that provides detailed information on the chemical elements. It is a port of GPeriodic to C++ and gtkmm, and it offers an improved UI, an updated and corrected data set, a better data format, a list view, and easier coloration.

GPeriodic: GPeriodic is a periodic table application for GNU/Linux. It allows you to browse through a periodic table of the elements, and view detailed information on each of the elements. 118 elements are currently listed.

GROMACS: GROMACS simulates molecular dynamics. It is primarily designed for biochemical molecules like proteins and lipids that have many complicated bonded interactions, but since it is extremely fast at calculating the nonbonded interactions (that usually dominate simulations) it is also used for research on non-biological systems, e.g. polymers. GROMACS is user-friendly, with topologies, parameter files, and error messages written in clear text format. There is a lot of consistency checking, but no scripting language: all programs use a simple interface with command line options for input and output files.

Gabedit: 'Gabedit' is a graphical interface to the Molpro and Gaussian computational chemistry packages, running locally or on a remote server. It includes a 3D molecule editor and viewer. Most major molecular file formats are supported, and graphics can be exported in many formats.

Gdpc: 'gdpc' is a tool for visualising the output files of a molecular dynamic simulation. It can be customized to read almost any input file format, animate it, and output images of each frame.

GenChemLab: 'GenChemLab' is an OpenGL-based application intended to simulate several common general chemistry laboratory exercises. It is meant to be used to help students prepare for actual lab experience. Supported experiments include titration, calorimetry, freezing point depression, vapor pressure, electrochemistry, and spectrophotometry.

Ghemical: Ghemical is a molecular modelling software package with a GUI (one for the GLUT library, and another for GNOME), and some nice 3D-visualization tools. It supports methods based on both molecular mechanics and quantum mechanics (using MOPAC7, and MPQC for QM). The geometry optimization (for MM and QM) and molecular dynamics (for MM) algorithms are included.

ImageJ: ImageJ is a public domain Java image processing program inspired by NIH Image for the Macintosh. It runs, either as an online applet or as a downloadable application, on any computer with a Java 1.4 or later virtual machine.
