[QE-users] absence of DOS above Fermi level

Dear QE team and users

I ran qe to get the DOS for spin polarized case after writing the 
required scf, nscf, and DOS files.

However, DOS plot looks strange such that the spin-up density of states 
above EF were almost absent!!!!!!!

I attached with this message the following files:

scf, nscf,  and dos files besides the dos_plot.

Thanks a lot in advance for your help.
