WebNov 25, 2024 · If you consider phono3py for use, I recommend the later approach to be consistent. One more note, if you use the later case, the option you need to create FORCE_SETS is not '--f' (double-dash) but '-f' (one dash). Then for the installation of phono3py, it is not recommended to mix up conda and pip. WebThis option requieres phonopy to be correctly installed and FORCE_SETS file has to be calculated first. The result is a set of phonon mode projections (one for each phonon) which are either displayed in the screen in different windows or stored in a file (one column for each phonon) sorted from lower to higher frequency.
