### How to plot the band structure of GW using o.qp file

Posted:

**Tue Oct 30, 2018 7:40 am**Dear YAMBO developer,

I calculated a simple GW calculation with yambo 4.0.4 (or 4.1.1) following command line for GWA

../yambo -g n -p p -k hartree . I get a file o.qp with:

# K-point Band Eo E-Eo Sc|Eo

but I don't know how to get the band gap value and how to plot the band structure of the system?

Also, what's the information can I get it from it.

Best,

Lamia
