Mapping DPD beads to atomistic

I have a CHARMM36 parameterized polymer which I would like to further study using DPD. I am new to LAMMPS and could not find any tutorial on how to map a DPD bead to a group of atoms and parameterize the beads in LAMMPS. Can anyone please point me to a tutorial on how to perform this.


This is not at all a LAMMPS question, but a question about creating a coarse grain model. You have to study the published literature to see how people have applied coarse graining for your specific type of application and then follow the most suitable example.
