How to convert the wrapped version of cell into LAMMPS data file?

Hello all,

I know this is a warning, and it doesn’t stop the simulation, but I faced some other warnings like “Dihedral Problem: …” that I think is a consequence of " Inconsistent image flag".

Thank you very much.

The warning is harmless in many simulations. So unless you see
it is causing you problems, you can likely ignore it.

If your graphene layers have bonds and span the periodic box
then there is no way to have fully consistent image flags.
