Plugin fails simulation on protein-ligand complex system

[ghost]

"""
I would to ask a question in using Gromacs pymol plugin.

Is it possible to do the simulation on protein-ligand complex system,
because when i call the complex in pymol workspace and starts doing
the simulation, i get the error (snapshot1 available).

Secondly, i did the topology generation, solvent, box, ion and energy
minimzation seperatly. Then i called the generated em.pdb into pymol
workspace, after unchecking the steps (snapshot2 available) and
running. I also get the error.

So, Does this plugin only work in protein alone, not protein-ligand complex.

help needed.
