Gwyddion is a modular SPM (Scanning Probe Microsope) data visualization and analysis tool. It can be used for all most frequently used data processing operations including: leveling, false color plotting, shading, filtering, denoising, data editing, integral transforms, grain analysis, profile extraction, fractal analysis, and many more. The program is primarily focused on SPM data analysis (e.g. data obtained from AFM, STM, NSOM, and similar microscopes). However, it can also be used for analyzing SEM (scaning electron microscopy) data or any other 2D data.

The FOX (Free Objects for Crystallography) program is made for determining crystal structure ab initio from diffraction data (mostly powder diffraction). It is built on an object-oriented crystallographic computing library called ObjCryst++. FOX features a graphical interface, including a 3D OpenGL display of the crystal structure. It provides a versatile description of the crystal structures (such as atoms, molecules, and polyhedra). Special positions and overlapping atoms are automatically handled without any a priori knowledge.

APBS is a software package for the numerical solution of the Poisson-Boltzmann equation (PBE), one of the most popular continuum models for describing electrostatic interactions between molecular solutes in salty, aqueous media. Continuum electrostatics plays an important role in several areas of biomolecular simulation, including simulation of diffusional processes to determine ligand-protein and protein-protein binding kinetics, implicit solvent molecular dynamics of biomolecules, solvation and binding energy calculations to determine ligand-protein and protein-protein equilibrium binding constants and aid in rational drug design, and biomolecular titration studies.

PDB2PQR is a Python software package that automates many of the common tasks of preparing structures for continuum electrostatics calculations, providing a platform-independent utility for converting protein files in PDB format to PQR format. These tasks include adding a limited number of missing heavy atoms to biomolecular structures, determining side-chain pKas, placing missing hydrogens, optimizing the protein for favorable hydrogen bonding, assigning charge and radius parameters from a variety of force fields.

gfit analyzes data using models. gfit lets the user create a model for virtually any type of system using a minimal amount of computer code. It is particularly useful for studying various systems in biophysics, biochemistry, and cell biology. The interface for gfit models specifies relationships between input and output variables in a rule-based fashion. It provides flexibility and allows the user to reuse same models for many related problems.

AGM Build is a molecular builder and conformational editor. It can be used for interactive model preparation for molecular dynamics simulations, including association of atom types and partial charges. It features geometry editing, lattice building, building of chain molecules (e.g. proteins), chains with predetermined conformations, and charges and atom types according to selected Force Field.

Penacho is a simulation software that calculates and draws the gas dispersion of a smokestack in the atmosphere. It consists of a GUI to enter air conditions, an atmospheric dispersion modeling solver, and an interactive 3D graphics engine. Penacho draws the plume evolution, the particles' deposition and the pollutant concentration distribution, as an isosurface and a grid plane for each coordinate axis. Penacho exports its simulation results as a text file, VTK structured points, or CSV (suitable for spreadsheets).
