Xavier,I did find the atom2cg.awk script on the downloads-> tools of the martini website, but there is no corresponding one for lipids. In any case I can probably figure out the mapping by trial and error, just based on inter-bead distances, but it would be nice to have it officially documented.
One of the MARTINI papers describes some of the mapping: dx.doi.org/10.1021/jp071097fI don't think there's a table for each lipid available anywhere, but that paper should give some impression of how things are connected, at least for a few simple lipids.

In order to do this, I'd prefer to have an EXACT definition of the aa-to-cg mapping. I cannot find this, only an imprecise graphic, in the MARTINI paper; the martini.itp file doesn't appear to list which heavy atoms are represented by each CG bead either. For example, I'm looking for something like: 'NC3' : ['C1', 'C2', 'C3', 'N4', 'C5', 'C6'], 'PO4' : ['O7', 'P8', 'O9', 'O10', 'O11','C12'], 'GL1' : ['C13', 'O14', 'C15', 'O16'], 'GL2' : ['C32', 'O33', 'C34', 'O35'], etc. For some atoms it's obvious which MARTINI groups they belong in, but others on the borderline are not obvious. For example, does C12 belong in PO4 or GL1? Anybody have a master list like this? Thanks, Mike-- ====================================Michael D.
