## Mission

Our goal is to provide a free package to construct, view and analyse atomic structures, as powerful and simple to use as possible.

GAMGI aims to be useful for: 1) the scientific community working in atomistic modelling, who needs a graphic interface to build and analyse atomic structures; 2) the scientific community at large, who needs a graphic interface to study atomic structures and to prepare images for presentations; 3) teaching the atomic structure of matter in schools and universities, even inviting students to run GAMGI at home; 4) science promotion, in exhibitions and science museums.

## Achievements

GAMGI can determine any point group of symmetry, can build crystals for any space group of symmetry, can build Random Close Packing structures, Voronoi and coordination polyhedra for arbitrary structures. GAMGI comes with comprehensive atomic data, including ionic radius and isotopic data. GAMGI can handle an arbitrary number of independent windows, layers (with different referentials, projections, viewports and visibilities), lights (directional, positional and spot), 3D text fonts (extruded and stroked). Actions can be performed in a single object or in a list of objects previously selected. GAMGI comes with detailed but concise documentation, just one click away for each task.

## Shortcomings

Currently GAMGI cannot handle alpha helix or beta sheet protein secondary structures, cannot calculate struture factors or diffraction patterns, cannot calculate orbitals, cannot show data graphics, cannot handle .pdb, .jmol and .cif files, cannot export or import coordination or Voronoi polyhedra. Support to build molecular structures is sketchy.

## Requirements

GAMGI can be installed on any computer running Linux/Unix with the standard X Window System. GAMGI requires the following libraries: Gtk, Mesa, Gtkglext, Expat and Freetype. GAMGI 0.14.8 or above requires GTK 2.18 to compile. To run properly, GAMGI requires a graphics environment with at least 16 bits per pixel, plus a 3-button mouse.
