BALLView provides fast OpenGL-based visualization of molecular structures, molecular mechanics methods (minimization, MD simulation using the AMBER, CHARMM, and MMFF94 force fields), calculation and visualization of electrostatic properties (FDPB) and molecular editing features.

BALLView can be considered a graphical user interface on the basis of BALL (Biochemical Algorithms Library) with a focus on the most common demands of protein chemists and biophysicists in particular. It is developed in the groups of Hans-Peter Lenhof (Saarland University, Saarbruecken, Germany) and Oliver Kohlbacher (University of Tuebingen, Germany). BALL is an application framework in C++ that has been specifically designed for rapid software development in Molecular Modeling and Computational Molecular Biology. It provides an extensive set of data structures as well as classes for Molecular Mechanics, advanced solvation methods, comparison and analysis of protein structures, file import/export, and visualization.

This program should convert CASTEP's .check, .castep_bin, orbitals and .cell to various other formats, particularly so that they can be visualised with Jmol, XCrysDen, gnuplot and other programs. It can extract charge and spin densities, wavefunctions, symmetry operations, and much else besides. It also interfaces with Abinit, Quantum Espresso, Siesta, VASP, and other electronic structure codes.

The code can also manipulate .cell and .pdb files, building supercells, performing shifts, adding vacuum and rolling nanotubes.

A Python library that provides parsers for computational chemistry log files. It also provides a platform to implement algorithms in a package-independent manner.

This package contains helper scripts for end users.

If you are looking for the unit tests and data files managed by cclib, they are distributed separately as in non-free package cclib-data.

Gabedit is a graphical user interface to computational chemistry packages like:

• MPQC
• GAMESS-US
• Gaussian
• Molcas
• Molpro
• Q-Chem

These Ab Initio software packages might run locally or on a remote server (supporting FTP, RSH and SSH). Gabedit can display a variety of calculation results including most major molecular file formats. The advanced "Molecule Builder" allows one to rapidly sketch in molecules and examine them in 3D. Graphics can further be exported to various formats, including animations.

slurm-wlm-torque and gridengine-client are workload managers which provide wrappers for PBS commands. Gabedit also allows one to configure it for any other workload manager.

GaussSum parses the output files of ADF, GAMESS, GAMESS-UK, Gaussian, Jaguar and PC GAMESS calculations to extract useful information.

GaussSum uses GNUPlot to display the progress of geometry optimisations, density of states spectrum, UV-VIS spectra, IR spectra, Raman spectra, and electron density difference maps. It can also display all lines containing an arbitrary phrase and more.

Jmol is a Java molecular viewer for three-dimensional chemical structures. Features include reading a variety of file types and output from quantum chemistry programs, and animation of multi-frame files and computed normal modes from quantum programs. It includes with features for chemicals, crystals, materials and biomolecules. Jmol might be useful for students, educators, and researchers in chemistry and biochemistry.

File formats read by Jmol include PDB, XYZ, CIF, CML, MDL Molfile, Gaussian, GAMESS, MOPAC, ABINIT, ACES-II, Dalton and VASP.

PyCIFRW provides support for reading and writing CIF (Crystallographic Information Format) files using Python.

The specifications found in Vol G of the International Tables for Crystallography were used as a reference for CIF 1.0/1.1 syntax. http://dx.doi.org/10.1107/S1600576715021871 was used as the CIF 2.0 reference.

TRAVIS (Trajectory Analyzer and Visualizer) is a free tool for analyzing and visualizing trajectories from all kinds of Molecular Dynamics or Monte Carlo simulations. The aim of TRAVIS is to collect as many analyses as possible in one program, creating a powerful tool and making it unnecessary to use many different programs for evaluating simulations. This should greatly rationalize and simplify the workflow of analyzing trajectories. The following analysis functions are available:

Static (time independent) Functions:

• Radial, Angular, Dihedreal or Combined Distribution Function
• Point-Plane or Point-Line Distance Distribution
• Plane Projection Distribution
• Fixed Plane Density Profile
• Density, Spatial or Dipole Distribution Function

Dynamic (time dependent) Functions:

• Velocity Distribution Function
• Mean Square Displacement / Diffusion Coefficients
• Velocity Autocorrelation Functions
• Vector Reorientation Dynamics
• Van Hove Correlation Function
• Aggregation Functions (DACF, DLDF, DDisp)

Spectroscopic Functions:

• Calculate Power Spectrum
• Calculate IR Spectrum
• Calculate Raman Spectrum

TRAVIS can read trajectory files in XYZ, PDB, LAMMPS or DLPOLY format.

Viewmol is able to graphically aid in the generation of molecular structures for computations and to visualize their results.

At present Viewmol includes input filters for Discover, DMol3, Gamess, Gaussian 9x/03, Gulp, Mopac, PQS, Turbomole, and Vamp outputs as well as for PDB files. Structures can be saved as Accelrys' car-files, MDL files, and Turbomole coordinate files. Viewmol can generate input files for Gaussian 9x/03. Viewmol's file format has been added to OpenBabel so that OpenBabel can serve as an input as well as an output filter for coordinates.

XCrySDen is a crystalline and molecular structure visualisation program, which aims at display of isosurfaces and contours, which can be superimposed on crystalline structures and interactively rotated and manipulated. It can run on most UNIX platforms, without any special hardware requirements.

XCrySDen allows for real-time capture of display. Several movie encoders are supported, in particular for Animated-GIF convert (imagemagick), gifsicle, or whirlgif are necessary. For AVI/MPEG mencoder or ppmtompeg (netpbm) is required. For window dumps either imagemagick or xwd (x11-apps) needs to be present.
