Thank you for your answer. No they are not the same, you fint here in attachement that when i use ibrav=0 and I define the cell parameter for sur, I find this fillings with this same range of x.

They look pretty much the same to me, except being plot with a different range along x -- Lorenzo Paulatto - Paris On Mar 3 2021, at 1:55 pm, sally issa <sally.is...@outlook.com> wrote: I try to calculate the density of state of Nb which is stable in centered cubic. To do this I use ibrav = 0 and identify the cell_parameter. but with ibrav = 0 I get a number of electrons from the shell d = 7 electrons (instead of 10). I tried to do this with ibrav = 3 which is good for the centered cuubic (well defined in pw.x quantum espresso) and I remove the cell_parameter of course. I get a good number of electrons at the level of the layer d. so I would like to know please what is the difference at the level of ibrav = 0 and ibrav = 3 which affects the result of the number of electron. SEEN that if you put the input of ibrav = 0 or that of ibrav = 3 on xcrysden it gives you a well-formed centered cubic structure.
