We are proud to introduce version 5 of CAMPARI. We have added a number of new features, most notably a Python interface for interpreting user-supplied code (with the help of ForPy), a novel trajectory storage standard (with the help of libpqxx/PostgreSQL), and a module for performing transition path theory. Naturally, CAMPARI continues to provide the reference implementation of the ABSINTH force field paradigm and implicit solvation model. CAMPARI is a joint package for performing and analyzing molecular simulations, in particular of systems of biological relevance. It focuses on a wide availability of algorithms for (advanced) sampling and is capable of combining Monte Carlo and molecular dynamics in seamless fashion. CAMPARI offers the user a very high level of control over all implemented features. For more information and features, please refer to the project's homepage at http://campari.sourceforge.net/V5

MEMBPLUGIN is a membrane analysis tool for molecular-dynamics simulations. It is a collection of visual and command-line tools that can be run within the Visual Molecular Dynamics (VMD) environment to analyze biomolecular simulations of lipid bilayers.

An open-source software to convert SDF files into TINKER XYZ files (and viceversa) with automatic assignment of MMFF94 atom types, bond types and charges

xPyder is a PyMOL plugin to analyze and visualize on the 3D structure dynamical cross-correlation matrices (DCCM), linear mutual information (LMI), communication propensities (CP), intra- and inter-molecular interactions (e.g. PSN), and more, to produce highly customizable publication-quality images. xPyder identifies networks (using concepts from graph theory, such as hubs and shortest path searching), compares matrices and focuses the analysis on relevant information by filtering the data using a modular, user-expandable plugin system that takes advantage of structural and dynamical information, contributing to bridge the gap between dynamical and mechanical properties at the molecular level.

AutoMap takes a series of poses obtained from molecular docking and applies the site, epitope and conformational mapping techniques to the poses to select likely ligand binding modes.

An ensemble of mathematical model is presented that all show diauxic growth behaviour of a bacterial culture. Carbon catabolite repression (CCR) is the main mechanism controlling carbohydrate uptake in bacteria, and therefore also controlling whether or not different carbon sources are metabolized in parallel or sequentially. Although described as a paradigm of the regulation of bacterial metabolism, the underlying mechanisms remain controversial. The models in the ensemble can be categorized according to regulatory, stoichiometric, and physiological constraints and differ from each other on only a single aspect. We distinguish four groups of models: (1) flux balance models that only define reaction kinetics for substrate uptake and by-product excretion, (2) kinetic models without and (3) kinetic models with regulation on the metabolic and/or genetic level, and (4) resource allocation models.

This python package aims to help people set up and analyze molecular dynamics simulations in aqueous-organic solvent mixtures. See D. Alvarez-Garcia et al. Journal of Medicinal Chemistry, 2014.

We here present a novel computer algorithm, called AutoClickChem, capable of performing many click-chemistry reactions in silico. In silico modeling of click-chemistry products may prove useful in rational drug design and drug optimization.

MDcons is a tool to analyze conserved contacts during Molecular Dynamics (MD) simulations of Protein, Rna, Dna & Ligand based complexes. The input is either a Molecular Dynamics trajectory or a set of snapshots. The input can also be a single snapshot. The outputs are (1) map of most/less frequently conserved contacts during MD (2) a list of most/less frequently conserved contacts during MD.

Molecular Interaction Potential Generator MIPGEN is a python program that will calculate Molecular Interaction Potential grids over a given molecule, that could be either a protein or a small organic compound (drug). The output will be a series of grids with DX format (*.dx) that the user will be able to visualize using any Molecular visualization program like VMD, PyMol, Chimera... For more information on dependencies and usage, please read the Documentation. Users are welcome to post any bug or request under BUGS & REQUESTS menu. (sourceforge account will be needed).

Besides all their conformational degrees of freedom, drug-like molecules and natural products often also undergo tautomeric interconversions. Compared to the huge efforts made in experimental investigation of tautomerism, open and free algorithmic solutions for prototropic tautomer generation are surprisingly rare. The few freely available software packages limit their output to a subset of the possible configurational space by sometimes unwanted prior assumptions and complete neglection of ring-chain tautomerism. MolTPC provides an adjustable and fully automatic approach for this problem. The original publication can be found on http://onlinelibrary.wiley.com/doi/10.1002/jcc.23397/full.

An open-source software aimed at computing cavity accessibility in cyclodextrin derivatives

QDC (quick direct-method controlled) is an optimized exact implementation of the Gillespie's direct-method. It is designed for biochemical simulations when there is the need of dynamic parameters whose values can change during the simulation.

Stochastic Pi Machine (SPiM), created by Microsoft, is a programming language for modeling biological processes. Two tools are available from Microsoft for simulation. A web application Visual SPiM, and a destkop application SPiM Player. Both simulation tools require to be run on a Windows platform. Fortunately Microsoft has also released a command line version for Linux and Mac OS based on OCAML however this version will only output a CSV file for the simulation results. SPiM2Eclipse provides a bridge for those running SPiM from the command-line by allowing simulations to be completed by a single click, displaying an embedded plot of the results. Features: -As an Eclipse plugin you have all of the powerful features of Eclipse available to you. -Syntax color highlighting -One-click simulation with plotting For more information on SPiM see the offical project website at: http://research.microsoft.com/en-us/projects/spim/

TrajLab (which stands for TRAJectory LABoratory) consists of two sets of MATLAB program packages. While subproject MolDynSim deals with generation of molecular trajectories (and other aspects of molecular simulation), subproject MetaStable is dedicated to the analysis of molecular trajectories by detecting metastable conformations (as well as other analysis techniques). Note that each of the two sub-projects has its own SVN repository, wiki, tracker, etc: Probably TrajLab is the first attempt for a general purpose molecular simulation package in MATLAB. While the authors are aware that many other highly specialized and highly optimized program packages for the same purpose exist (e. g. AMBER, GROMACS, NAMD, etc.), the MATLAB environment offers easy access to manipulating the codes, testing novel algorithms, non-standard force fields and performing all kinds of numerical experiments. To be used mainly in teaching!

chemkit is an open source software library for chemistry applications, particularly in the areas of cheminformatics, molecular visualization and molecular modeling.
