phonopy -p band-pdos.conf -s Adding the -s tag will write out a PDF. To interpret the PDOS (to add labels to each PDOS line), you also need to see the PDOS plot by itself. Create a PDOS.conf file that contains: DIM = 2 2 2 MP = 13 13 13 PDOS = AUTO and type this command: phonopy -p pdos.conf -s ADDITIONAL CORRECTIONS: WebPhonopy is an open source package for phonon calculations at harmonic and quasi-harmonic levels. Phono3py is another open source package for phonon-phonon interaction and lattice thermal conductivity calculations.
