You need to run again pw.x with either calculation=‘bands’ or calculation=‘nscf’ to reidiagonalize the Hamiltonian along a specified
path in the Brillouin zone. Follow Examples/PW/example01
    This example shows how to use pw.x to calculate the total energy
    and the band structure of four simple systems: Si, Al, Cu, Ni.
