Query Regarding Phonon Dispersion

Hey all,

I am interested in evaluating the phonon dispersion curves for Graphene , using LAMMPS on Ubuntu. As of now I have correctly followed all the instructions given in https://code.google.com/archive/p/fix-phonon/wikis/InstructionOnPostprocessingCode.wiki. And have installed the three libraries clapack, spglib and tricubic. But I don’t know the way ahead. Can someone guide me through the next steps?

I would be grateful to you for your help.

please see the tools/phonon/README file
