I am not aware of the model, though it might be somewhere around. If you would have to make it my suggestion would be to change the SP1 bead to a SC1 (to remove the -OH inclusion) and add an extra NQa bead to that bead. This would be the same mapping as PO4, but I dont think we can make the distinction in Martini. Let us know how it turns out.

Cheers!

Thanks Bart for the quick reply. You mean to say Qa bead and not NQa.

Yes, I put the N there to specify that is should be a normal sized bead and not an S like the others in the ring.
