[Wien] electron occupancy in dmatup/dn

The trace of the dmat is about 0.38 f electrons for the first atom. You 
should see the same number in the corresponding case.scf2  :QTL  line.

It looks very small for U, in particular when you say that the other 
spin is similar, but I don't know any details.
First thing to do is always a regular PBE calculations. What are your 
results there ?

Please follow ALWAYS the recommended procedure:

init -sp
runsp
save pbe
x lapwdm -up/-dn
runsp -orb
