How to plot Cumulative kappa using frequency as x axis rather than mfp?

[abchaoming1]

Dear developers and users,
I am using ALAMODE to calculate the cumulative kappa with analyze_phonons.py code. I found no options or prompts to use frequency as the x-axis for plotting the cumulative kappa in the analyze_phonons.py(maybe I missed something? It is all about the mfp as the x-axis). How can I employ the frequency as the x-axis to plot?

Thanks!

I think the Thermal conductivity spectrum may help you solve this problem. If you integrate the Thermal conductivity spectrum, the resulting outcome should be Cumulative kappa vs frequency.
