band structure

Dear All,

I am actually trying to calculate the band structure of some actinide compound. As it is known from the VASP manual, the band structure should be recalculated with CHGCAR from the previous run. However, the Fermi energies differ in both the calculations whereas one electron energies are the same, at least at gamma point. Then one can not interpret the band structure properly. Could anyone clarify that situation?

Thank you in advance.

if a different set of k-points is used, the Fermi levels may well differ slightly.
