A recent study by Carpenter, Lopez and coworkers nicely characterized the phase behavior of Martini DPPC/DOPC/cholesterol ternary mixtures. General Martini parameters correctly captured a large fraction of the phase diagram, but parameters optimized against CHARMM DOPC and DPPC simulations could better capture some of the details, especially close to the critical point.
The new lipid parameters specifically tuned to CHARMM DOPC and DPPC can be found here and in the Martini lipid parameter list: DPPC and DOPC.

Together with several co-authors, we wrote a comprehensive review (>700 references) on computer simulations of cell membranes. In this field, we are witnessing a transition from simulations of simpler membrane models to multicomponent systems, culminating in realistic models of an increasing variety of cell types and organelles. Here, we review the state of the art in the field of realistic membrane simulations and discuss the current limitations and challenges ahead.

Boyd and May have deleloped a new tool called BUMPy. The tool allows you to create curved lipid bilayers, combining flexibility of shape, force field, model resolution, and bilayer composition. The tool is avialable online. For details, including many Martini based applications, check the paper: Boyd & May, JCTC, in press, DOI:10.1021/acs.jctc.8b00765
