Dear all,

Recently, I want to do MD simulation on a protein and ligand compound
using NAMD2.7 with CHARMMb35 force field.
But I have no idea of to get topology and parameter file for the ligand.

Would you please give me some suggestions?

The name of my ligand is Riboflavin(VB2).
Sorry, the picture of my ligand can't be loaded.

Thank you very much!

Jianing
