Dear Prof. Blaha,
 
Thanks for your reply. My E-windows is the same as I did scf calculations, that's -7.0 to 2.0.
 
Best,

During the self-consistent calculation, I didn't get any QTL-B values, however, after I did the "x lapw2 -qtl" I found a big (around 10) QTL-B values in file case.scf2. What did this QTL-B value come from? Except this weird QTL-B value, every thing is Ok, I mean the total number of electrons, and the Fermi level.

This comes from unoccupied states at high energy (what was your E-window
?)
You can ignore that, except when you are explicitly interested in the
unoccupied DOS (optic, absorption spectra)
