projected phonon linewidth on phonon spectra

Post by simba2828 »

Dear EPW experts,

Could anyone please tell me how to get a projected phonon linewidth on phonon specta according to the following figure?

What are the necessary input tags in epw calculation and what is the basic gnuplot script?
I can plot the linewidth along some k-path using:

plot "linewidth.phself" u 1:4 every 3::2 w l lw 2

but how to get a projected linewidth weights on phonon dispersion.

Thank you,
Shubham
