Debian Edu Chemistry packages

Avogadro is a molecular graphics and modelling system targeted at molecules and biomolecules. It can visualize properties like molecular orbitals or electrostatic potentials and features an intuitive molecular builder.

Features include:

• Molecular modeller with automatic force-field based geometry optimization
• Molecular Mechanics including constraints and conformer searches
• Visualization of molecular orbitals and general isosurfaces
• Visualization of vibrations and plotting of vibrational spectra
• Support for crystallographic unit cells
• Input generation for the Gaussian, GAMESS and MOLPRO quantum chemistry packages
• Flexible plugin architecture and Python scripting

File formats Avogadro can read include PDB, XYZ, CML, CIF, Molden, as well as Gaussian, GAMESS and MOLPRO output.

Chemtool is a GTK+ based 2D chemical structure editor for X11. It supports many bond styles, most forms of text needed for chemical typesetting and splines/arcs/curved arrows.

Drawings can be exported to MOL and PDB format, SVG or XFig format for further annotation, as a PiCTeX drawing, as a bitmap or as Postscript files (several of these through XFig's companion program fig2dev).

The package also contains a helper program, cht, to calculate sum formula and (exact) molecular weight from a chemtool drawing file. Cht can either be called directly by Chemtool or on the console.

EasyChem is a program that helps you creating high quality diagrams of molecules and 2D chemical formulas that can be exported to PDF, PS, LaTeX and fig.

EasyChem was originally developed to create diagrams for chemistry books and is now frequently used for this purpose in commercial and non-commercial chemistry-related books.

A package to reorganize menu branches in order to get a structure easy to use for teachers and students.

GChemPaint is an editor for 2D chemical structures with a multiple document interface. Drawn molecules can be searched at NIST Webbook and PubChem.

A GTK+ based program for the display and manipulation of isolated molecules, periodic systems and crystalline habits. It is in development, but is nonetheless fairly functional. It has the following features:

• Support for several file types (CIF, BIOSYM, XYZ, XTL, MARVIN, and GULP)
• A simple molecular creation and manipulation tool
• A dialogue for creating starting configurations for molecular dynamics simulations
• Assorted tools for visualization (geometry information, region highlighting, etc.)
• Animation of BIOSYM files (also rendered animations, see below)

GDIS also allows you to perform the following functions through other packages:

• Model rendering (courtesy of POVRay)
• Energy minimization (courtesy of GULP)
• Morphology calculation (courtesy of cdd)
• Space group processing (courtesy of SgInfo)
• View the Periodic Table (courtesy of GPeriodic)
• Load additional filetypes, such as PDB (courtesy of Babel)

GPeriodic is een klein X/GTK+-gebaseerd programma waarmee je door de periode tabel van chemische elementen kan bladeren, en van elk element kan je gedetaileerde informatie opvragen. De tabel bevat 118 elementen.

Kalzium is a full-featured chemistry application, including a Periodic Table of Elements, chemical reference, chemical equation solver, and 3D molecule viewer.

This package is part of the KDE education module.

PyMOL is a molecular graphics system targeted at medium to large biomolecules like proteins. It can generate high-quality publication-ready molecular graphics images and animations.

Features include:

• Visualization of molecules, molecular trajectories and surfaces of crystallography data or orbitals
• Molecular builder and sculptor
• Internal raytracer and movie generator
• Fully extensible and scriptable via a Python interface

File formats PyMOL can read include PDB, XYZ, CIF, MDL Molfile, ChemDraw, CCP4 maps, XPLOR maps and Gaussian cube maps.

RasMol is a molecular graphics program intended for the visualisation of proteins, nucleic acids and small molecules. The program is aimed at display, teaching and generation of publication quality images.

The program reads in a molecule coordinate file and interactively displays the molecule on the screen in a variety of colour schemes and molecule representations. Currently available representations include depth-cued wireframes, 'Dreiding' sticks, spacefilling (CPK) spheres, ball and stick, solid and strand biomolecular ribbons, atom labels and dot surfaces.

Supported input file formats include Protein Data Bank (PDB), Tripos Associates' Alchemy and Sybyl Mol2 formats, Molecular Design Limited's (MDL) Mol file format, Minnesota Supercomputer Center's (MSC) XYZ (XMol) format, CHARMm format, CIF format and mmCIF format files.

This package installs two versions of RasMol, rasmol-gtk has a modern GTK-based user interface and rasmol-classic is the version with the old Xlib GUI.
