Hi all. <br>As an update I calculated the bandstructure assuming that the negative rho has little effect on the final result, and then I got a bandstructure with a certain lines in it. I am hoping if anyone can tell me how to get all the k point for the nscf input, so I can get a more smooth bandstructure finally. Thank you.<br>
