I need some more information:

Are you using wien23 or an earlier version ?

What is your system (struct file), in particular what is atom 1; its RMT, ...

Such a large EF is rather unusual (except for 5f systems) and for sure the resulting E-parameters as you showed below must lead to ghostbands. Usually it is good to remove the LO for this atom and l-value, at least temporarily, but you must check at what energy would you expect the semicore state and you must not miss it, if it is a real low energy state. ....

Is this actually a hybrid calculation ? Does it happen in the first iteration ? Did you start a hybrid calc. from a converged PBE calculation ? ....

Dear Professor Blaha,

I tried to run calculations for hybrid functionality from libxc, but I get a GHOST BANDS error. The case.scf2 file states that for atom 1 with l=1, the energy parameters need to be changed.

:WARN : QTL-B value eq. 32.08 in Band of energy 1.68736 ATOM= 1 L= 1
:WARN : You should change the E-parameter for this atom and L-value in case.in1 (or try the -in1new switch)
The Fermi level in scf2 is
:FER : F E R M I - ENERGY(TETRAH.M.)= 1.8321578843
I tried setting it to 1.632 instead of the default 0.3 in case.in1, but that didn't fix it. Then I tried to remove the values that have similar energy values in case.scf1 from the case.in1 file (reducing the number of n choices), but this did not lead to a positive result.
:E1_0001: E( 1)= 0.7000
              APW+lo
:E1_0001: E( 1)= 0.4094 E(BOTTOM)= 0.409 E(TOP)= -200.000 3 -1 222
              LOCAL ORBITAL
When trying to change the energy parameters and set the in1new flag, an nband error appeared.


Thank you in advance,
Best Regards,
Natalia Andreeva.
