Dear James / Gleb,
This question seems too broad, perhaps. I don’t know that much about MARTINI, so I’m guessing instead of atoms you just have a bunch of points that each represent multiple atoms. In that case you could probably use any analysis that does not directly use exact atomic locations, atomic radii, or atomic point charges. Analyses that DO use those things include surface-area calculations, Find Clashes/Contacts, FindHBond.
Maybe you should just first think about what Chimera analysis you want to use, then just try it on your GC model and see if it works rather than trying to get some exhaustive list of what might work.
I hope this helps,
