[QE-users] problem with ph.x in calculating x-point phonon

[刘润福]

Hello everyone,
I am using Quantum ESPRESSO software to calculate the electron-phonon coupling coefficient, which is displayed in the ph.out output file:

Possibly too few bands at point 8 0.00000 0.00000 0.50000

Possibly too few bands at point 19 0.00000 0.00000 -0.50000

Possibly too few bands at point 473 0.0000 0.50000 0.0000

Possibly too few bands at point 746 0.00000 0.50000 0.00000
What is the cause of this, how to solve this problem, will it have an impact on the final result?
Thanks and Regards
