The molecular mechanics (MM) program Iphigenie provides a broad range of molecular dynamics (MD) methods and technologies, including polarizable force fields (PMM), the HADES reaction field, and QM/(P)MM hybrid simulations.

The Collaborative Computational Project for NMR (CCPN) provides tools and knowledge to maximise the impact of the biological NMR studies. The CCPN software facilitates data analysis and software integration. The project actively promotes the exchange of knowledge and provides training and best practices for the NMR community. CCPN also has a leading role in the development of a NMR data-sharing standard and coordination of NMR instrumentation proposals for RCUK and BIS. The 28 partners of CCPN jointly cover all aspects of biomolecular NMR and together they promote excellence in science in their respective fields.

Hydrogen-deuterium exchange coupled to mass spectrometry permits analysis of structural dynamics, stability, and molecular interactions of proteins. Resolving isotopic fine structure during mass spectrometry has been recently demonstrated to allow direct detection and quantification of deuterium incorporation distinct from peaks corresponding to non-deuterium incorporated natural abundance heavy isotopomers.

...At variance with other approaches, it is possible to analyse also processes in solution, e.g., chemical reactions in liquid water, since the distance metric is based on a Permutation Invariant Vector (PIV) that is symmetric under exchange of identical atoms or molecules, including on the same footing both solute and solvent degrees of freedom. The approach is general and the definition of PIV only requires to specify the range of interatomic distances that is relevant for the process under study. Alternatively, also the SPRINT topological coordinates can be employed, that are particularly suited for nanostructures. ...

PLASMAKIN is a package to handle physical and chemical data used in plasma physics modeling and to compute gas-phase and gas-surface kinetics data: particle production and loss rates, photon emission spectra and energy exchange rates.

REMD toolkit is designed as a C++ framework to build a replica-exchange molecular dynamics (REMD) program, suitable for solving the multiple-minima problem that prevents accurate estimation of thermodynamical properties.

A plugin for the Eclipse IDE implementing NumericalChameleon: a powerful numerical convertor, supporting more than 2300 units in 78 categories (physics, radixes, exchange rates, unicode, etc). Fully integrated in the Eclipse IDE (refactoring, copy/paste)

...The supported operations involve trajectory coordinate transformation to the COM system, Cartesian coordinate transformation to selected internal coordinates and to projected normal mode coordinates, trajectory merging, selecting subsets of trajectory frames, selecting subsets of atoms, permuting atoms, etc. Analysis tools involve 1D, 2D and 3D data binning (histograms), volumetric data handling, etc. A small library, libmd, is an abstraction layer that serves data exchange among different tools.
