[lammps-users] question of coarse-grained MD

Hi, everyone.

It looks like coarse grained molecular dynamics can be done with LAMMPS.
But I hardly find an example including input script, data file, and etc for CGMD with LAMMPS.
So, I was wondering if anybody could provide me sample input script, data file, and etc for CGMD?

by the way,
for CGMD, what the atom type should be ?
Can I assign charge onto a coarse-grained bead?

Thank you !

Best,
Ed.
