With an intuitive user interface, photorealistic graphics, and support for affordable virtual reality headsets, shutter glasses, autostereoscopic displays, and input devices, YASARA creates a new level of interaction with the 'artificial reality', that allows you to focus on your goal and forget about the details of the program. YASARA is powered by PVL (Portable Vector Language), a new development framework that provides performance way above traditional software. PVL allows you to visualize even the largest proteins and enables true interactive real-time simulations with highly accurate force fields on standard PCs, making use of GPUs if available. You can push and pull molecules around and work with dynamic models instead of static pictures.

ArgusLab is a molecular modeling, graphics, and drug design program for Windows operating systems. It’s getting a little dated by now, but remains surprisingly popular. To date, there are more than 20,000 downloads. ArgusLab is freely licensed. You don’t need to sign anything. You can use as many copies as you need if you are teaching a class where your students might benefit from using ArgusLab. You are not allowed to redistribute ArgusLab from other websites or sources. However, you may link to this website from your own websites if you like. A low-key effort is currently underway to port ArgusLab to the iPad. In addition, I’ve done some work with the Qt cross-platform development environment in an effort to support Mac, PC, and Linux.

It is a versatile package for simulating the Newtonian equations of motion for systems with hundreds to millions of particles, with a strong focus on materials modeling, biomolecular simulation, and particle-based systems. GROMACS is primarily designed for biochemical molecules such as proteins, lipids, and nucleic acids, which involve many complicated bonded interactions, but its speed in calculating nonbonded interactions also makes it useful for non-biological systems such as polymers and other materials. It can model ensembles of particles in liquid, solid, or gaseous states and supports a wide range of molecular dynamics workflows, from basic energy minimization and equilibration to production simulations and detailed trajectory analysis.

NAMD is a parallel molecular dynamics code designed for high-performance simulation of large biomolecular systems. Based on Charm++ parallel objects, it scales from desktop and laptop computers to high-end parallel platforms, hundreds of cores for typical simulations, and beyond 500,000 cores for the largest simulations. NAMD is built for researchers who need to simulate large molecular systems efficiently while preserving compatibility with widely used molecular modeling workflows. It uses the popular molecular graphics program VMD for simulation setup and trajectory analysis, and it is file-compatible with AMBER, CHARMM, and X-PLOR. It is designed to support biomolecular simulations involving proteins, membranes, nucleic acids, solvents, ions, and other molecular systems where atomic interactions and time-dependent motion need to be studied in detail.

ESPResSo, the Extensible Simulation Package for Research on Soft Matter, is a highly versatile open source simulation package for performing and analyzing scientific molecular dynamics and Monte Carlo many-particle simulations. It is designed as a universal tool for simulating a variety of soft matter systems, especially coarse-grained atomistic or bead-spring models used in physics, chemistry, molecular biology, and process engineering. ESPResSo can be used to simulate polymers, liquid crystals, colloids, polyelectrolytes, ferrofluids, gels, biological systems, DNA, lipid membranes, bacterial motion, and super-capacitors. In coarse-grained models, a group of atoms or molecules is treated as a single bead, allowing researchers to investigate larger time and length scales than would be practical with fully atomistic simulations. ESPResSo supports classical molecular dynamics simulations in different statistical ensembles.

Swiss-PdbViewer (aka DeepView) is an application that provides a user-friendly interface allowing to analysis of several proteins at the same time. The proteins can be superimposed in order to deduce structural alignments and compare their active sites or any other relevant parts. Amino acid mutations, H-bonds, angles, and distances between atoms are easy to obtain thanks to the intuitive graphic and menu interface. Swiss-PdbViewer (aka DeepView) has been developed since 1994 by Nicolas Guex. Swiss-PdbViewer was initially tightly linked to SWISS-MODEL, an automated homology modeling server developed within the Swiss Institute of Bioinformatics (SIB) at the Structural Bioinformatics Group at the Biozentrum in Basel. However, the SWISS-MODEL web interface evolved to a point where it is now possible to use it directly for advanced modeling. Maintaining a direct interface with Swiss-PdbViewer is too complex and no longer supported.
