[QE-users] Error in routine bands (1): reading bands namelist

[Michal Bennar]

Hello, 

I have a problem that has been previously discussed, but I was unable to solve it or find a proper solution. I am experiencing a problem with 'bands.x' on my Ubuntu 22.04.2 LTS running on Windows 11. I was able to perform band calculations using pw.x, but when I attempt to use bands.x, I encounter the following error.

~/QE/Au_bands$ bands.x < Au_bands_pp.in |tee Au_bands_pp.out

All of my input files for pw.x have the same prefix, which is 'gold'  (prefix = 'gold').

I really appreciate anyone's help.
