dear,

I want to do MD simulation with lammps and I use amber force field (specifically ff91sb) for it. However, I have a problem with atom type in lammps data file. How can I add automatic atomic type (by another solfware/program?) that matches amber ff? My simulation has thousands of atoms and I try vmd but it seems that vmd doesn't support amber ff (or i need to do something before using vmd?).

Thank you!

Sincerely,

Dinh Loc.
