[QE-users] Regarding Tutorial Electron phonon coupling of Pb by S.Ponce

[Prarena Jamwal]

Dear all,

I was reproducing Electron-phonon coupling of Pb using Quantum Espresso by
S. Ponce. I am using Quantum Espresso v7.0.
In the tutorial, they have plotted phonon linewidth (γqν) along high
symmetry path using one of the elph.gamma files after matdyn.x analysis.
The plot shows a range of 0 to 60 GHz of γqν.
But the problem is I am getting 0 to 6 GHz on plotting the elph.gamma.X
file. I have used the same parameters. I have attached files too. Kindly
have a look.

Any help or suggestion would be appreciated.
