[Pw_forum] How to calculate inverse participation ratio (IPR) using espresso?

[Stefano de Gironcoli]

I guess what you may look at is the integral of |psi|^4 over your cell. There should be a post-processing tool computing local density of states (basically |psi|^2) that could be easily modified for your purpose

For finding mobility edge in my DOS plot, I'm willing to calculate the inverse participation ratio of the electronic states in the plot as a measure of localization. I'm wondering if there is any way to calculate IPR using Espresso output files.
