Dear LAMMPS users,

I need an urgent help regarding phonon dispersion curves using LAMMPS. I have downloaded the required three external libraries(tricubic,spglib and USER-PHONON) as well as obtained the executable “phana” and have also downloaded gnuplot, by following the instructions given in the manual as well as the README files.But I am not able to proceed further in obtaining a phonon dispersion for the four examples given in the examples/USER/phonon directory of LAMMPS. I want to obtain phonone dispersion curves for pentagraphene.

Can somebody please guide me through the proper commands and next steps in obtaining the same !!
I would be grateful to you for your help !

what do you mean by “i am not able”? what is the problem? the examples look like they are self contained and provide sufficient information in their corresponding README files.
