CPPTRAJ is a program designed to process and analyze molecular dynamics trajectories and relevant data sets derived from their analysis. CPPTRAJ supports many popular MD software packages including Amber, CHARMM, Gromacs, and NAMD.

GROMACS est un paquet polyvalent pour faire de la dynamique moléculaire, comme la simulation d'équations newtoniennes du mouvement de systèmes de millions de particules.

Il a été créé en premier lieu pour les molécules biochimiques comme les protéines et les lipides qui ont beaucoup d'interactions covalentes compliquées, mais comme GROMACS est extrêmement rapide pour calculer les interactions non covalentes (qui souvent dominent les simulations), beaucoup de groupes l'utilisent aussi pour la recherche sur des systèmes non biologiques, comme les polymères.

Ce paquet fournit des variantes pour l’exécution sur une seule machine et pour utiliser l’interface MPI sur plusieurs machines.

LAMMPS is a classical molecular dynamics code, and an acronym for Large-scale Atomic/Molecular Massively Parallel Simulator.

LAMMPS has potentials for soft materials (biomolecules, polymers) and solid-state materials (metals, semiconductors) and coarse-grained or mesoscopic systems. It can be used to model atoms or, more generically, as a parallel particle simulator at the atomic, meso, or continuum scale.

LAMMPS runs on single processors or in parallel using message-passing techniques and a spatial-decomposition of the simulation domain. The code is designed to be easy to modify or extend with new functionality.

ParmEd is a package designed to facilitate creating and easily manipulating molecular systems that are fully described by a common classical force field. Supported force fields include Amber, CHARMM, AMOEBA, and several others that share a similar functional form (e.g., GROMOS).

ParmEd is capable of reading and writing to a wide array of different file formats, like the Amber topology and coordinate files, CHARMM PSF, parameter, topology, and coordinate files, Tinker parameter, topology, and coordinate files, and many others. The expressive central data structure (the 'Structure' class) makes it easy to quickly and safely manipulate a chemical system, its underlying topology, and force field parameters describing its potential energy function.

There are two parts of ParmEd -- a documented API that one can incorporate into their own Python scripts and programs, and a GUI/CLI pair of programs that provides a means to quickly perform various modifications to chemical systems for rapid prototyping.

The API also provides bindings to the OpenMM library, permitting one to carry out full molecular dynamics investigations using ParmEd on high-performant hardware, like AMD and NVidia GPUs.

ProDy est un paquet de Python au code source ouvert pour l’analyse de séquences de dynamiques et de structures de protéines. Il permet une analyse comparative et la modélisation de dynamiques structurelles de protéines et de co-évolutions de séquences. L’IPA rapide et flexible de ProDy sert à une utilisation interactive ainsi qu’au développement d’applications. ProDy est aussi fourni avec plusieurs applications d’analyse et une interface graphique pour une analyse visuelle.

Versatile Object-Oriented Toolkit for Coarse-Graining Applications (VOTCA) is a modeling package for the analysis of molecular dynamics data, the development of systematic coarse-graining techniques, and methods used for simulating microscopic charge transport in disordered semiconductors.

Numerous molecular dynamics packages, including but not limited to GROMACS, ESPREesSo, and LAMPPS, can be used together with VOTCA.

This package contains user programs for the coarse-graining toolkit (CSG) and excitation transport toolkit (XTP).

DL_POLY Classic is a general purpose (parallel and serial) molecular dynamics simulation package.
