getting eliashberg function only for few bands and k points.
I am trying to get the eliashberg function for silicon using the method explained in the tutorial "Electron-Phonon effects in semiconductors: the band-gap and absorption spectrum of Silicon and Diamond". But I am getting it only for bands 1,2,7 and 8 at k point 1. I am not getting the data for the bands in between where band 4 is my top of valence band. However, I am able to generate the spectral functions of all bands. Can you please suggest me where I am doing wrong?
