Hello again, Elias and other friends

I calculated the band structure of 4-atom CoO with G-type
antiferromagnetism, the band structure seems good with GGA+U (U ~ 2 eV). I
also got from band that in the energy range *[-2 eV : Fermi level]*, dx2-y2
and dxy dominates the main features of band structure. I thus wanted to use
these bands to construct WF. However, after "grep :BAN case.scf2", it gave
the information (I wrote the last lines here):

Personally, I think *this file didn't show me the which bands span in the
energy range [-2 eV : Fermi level].* The calculations (in previous emails)
two days ago printed the band indices in valence bands in the case.scf
files, but this time it was not.  I know that I can find the requested
information from band.agr files, but this option slows down my jobs. My
question is how to find the band index in the interested energy windows in
a faster way*?* I also wander what rules WIEN2k code depends on to print
the information of band indices in specific energy windows in case.scf*
files?

With my best regards
Fang
