Hi;
So without calculating the band energies that you want in your "scf" calculations, you can not increase your window in the "bands" calculations.
I would again suggest to increase your nbnd, starting from scf.

Dear expert and all
I want to choose an energy window for my energy band calculation.
So I want to know that how to define energy window in my bands input file.
Already send in above mail.

Hi;
You can increase your "nbnd" in your scf calculations followed by bands calculations with the same nbnd.

Dear expert and all
I have done bands calculation , or fermi energy is -0.1382 Ry .
but not received energy bands above this fermi energy , only received bands till -0.18 Ry energy .
so, how can I calculate the above energy bands in my DFT calculation? I am using qe-6.3 .
input file also attached.
