MARTINI model development

The use of coarse-grained (CG) models in a variety of simulation techniques has proven to be a powerful tool to probe the spatial and temporal evolution of systems on the microscale, beyond what is feasible with traditional all-atom models.

The MD group is host of the popular MARTINI model, a versatile CG force field for biomolecular simulations. The overall aim of our coarse-graining approach is to provide a simple model that is computationally fast and easy to use, yet flexible enough to be applicable to a large range of systems. Example input files for many systems can be downloaded from http://cgmartini.nl. In collaboration with the group of Peter Tieleman at Univ. of Calgary, we continuously work on systematically improving and further extending of the force field.
