[QE-users] regarding error in bands name list

[Satyasiban Dash ph19d005]

Dear qe experts,
I use QE 6.4.1 on ubuntu pc configured for parallel running. i am trying to
calculate bandstructure of iron.I am able to get scf.out file and bands.out
file through pw.x, but i am unable to extract eigen value information using
bands.x. I run into some namelist error.
