[From Kennie Merz]:

There are 12-6 and 12-6-4 Ca(II) nonbonded parameters available, but they were designed to reproduce aqueous phase properties. How they will work with Ca(II) binding to an EF-hand is anyone's guess. This paper from the York lab highlights some of the challenges you might face: York & co-workers JPCB 2015, 119, 15460. Other than that MCPB.py is another way to go to build a bonded model. You have a super interesting problem, but some tuning will be in order if you want to go the nonbonded model route is my guess. Good luck!
