Martini metadynamics

Check out this paper, a nice example of how metadynamics can be combined with Martini for efficient sampling of protein-protein binding free energies:

Protein side chains

The team of Prof. Vogel has developed a fix to prevent side chains from flipping to the wrong side of beta strands. Soon to be implemented in martinize. For details, see:

A nice study by Wang and Deserno show that the pivotal plane in a Martini DMPC bilayer is located closer to the bilayer center in comparison to an atomistic bilayer. This has important consequences for the interpretation of the effect of curvature on membrane properties. For details, please consult the full paper:
