Check it out:
You have B and C atoms at the same position.
A X-ray structure is an "average" structure and they often
give 2 atoms at the identical position, but with a fractional
(eg. half+half) occupation.
You cannot have this in WIEN2k, as was discussed before.
Use supercells,.

No, SIC is not implemented (and does not work for Bloch states).
In addition: There is for sure NOTHING on the market, which is
even nearly as fast as mBJ and comparable accurate.

Dear Wien2k users,
Is there within the package implemented self-interaction correction
for improvement of band gaps
in semiconductors, e.g. GaAs, Si, by means of Perdew & Zunger PRB 23,
5048 (1981)?
We are seeking a cheaper alternative to the MBJ to study bigger
systems. What would you
recommend?

I know this error has occured several time bef
Thanks. I have plotted it out. Thanks very much.

In case it is not obvious, you need to change 0.6667 to 0.7 in
the cif file first.

Read your struct file, and you will see lines such as:
-2: X=0.6667 Y=0. Z=0.7500
-2: X=0. Y=0. Z=0.7500
This is a standard user error when not employing precise positions in
hexagonal when converting a cif. Your initialization would not
