Dear Forum,

I can able to calculate the lamda value for total dispersion using
lambda.x. But i need to calculate mode dependent lambda value and mode
dependent phonon line width.
I have small confusion, In elph file i can find lambda value and gamma
value. Can i separate these values manually and plot like as phonon
dispersion. Is this way will give fine result or not. Or is there any other

Any suggestion can be acceptable ...

Thanking you ...
