I've added an example on how to do the plot in the MgO example of the D3Q code,
note that it is not necessary to use any of the "anharmonic" features.
You will find it here:
https://github.com/anharmonic/d3q/tree/main/Examples/MgO
(https://link.getmailspring.com/link/4a29d35f-ed88-40f5-b280-31970fed7...@getmailspring.com/0?redirect=https%3A%2F%2Fgithub.com%2Fanharmonic%2Fd3q%2Ftree%2Fmain%2FExamples%2FMgO&recipient=dXNlcnNAbGlzdHMucXVhbnR1bS1lc3ByZXNzby5vcmc%3D)
i.e. you can get the phonon dispersion using d3_r2q.x and d3_q2r.x as shown in
the script, than plot the projected dispersion using the plot-projected.gp
script for gnuplot. This is actually the most tricky part, it may require some
thinking especially if you have more that 2 species.
It should work without any code modification with the d3_q2r.x and d3_r2q.x
codes that are included in QE 6.8
