[QE-users] Printing electron-phonon matrix elements using ph.x

Dear Experts,

Is there any way one can print the electron-phonon (elph) matrix elements for all the k-points together after nscf calculation. I am using the following script but it can print only one k point at a time. Is there any functionality in QE/PHonon which performs this?

&inputph
  tr2_ph=1.0d-14
  prefix='aiida'
  fildvscf = 'dvscf'
  outdir='./out/'
  fildyn='aiida.dyn'
  electron_phonon = 'prt'
  el_ph_sigma=0.04
  el_ph_nsigma = 25
  ldisp = .true.
  nq1 = 5
  nq2 = 5
  nq3 = 1
  start_q =1
  last_q =1
  trans = .false.
