Modeling and simulation


Biospring is a molecular simulation software based on a spring network model, including non-bonded interactions, especially designed for Interactive Molecular Dynamics by Olivier Delalande, Nicolas Férey, Alex Tek, Benoist Laurent and Marc Baaden

Collective Variables Module

The Collective Variables Module plugs into molecular dynamics simulation engines such as NAMD and LAMMPS or analysis tools such as VMD and provides flexible and powerful analysis and biasing on collective variables, including adaptive time-dependent biases. By Giacomo Fiorin (Temple University) and Jérôme Hénin.
