[Wien] band plot very strange

[Mary White]

Dear all wien2k users,
           I have some problems when I calculate the energy band. The space group is 152_P3121,which is hexagonal cell.
           The scf is OK. But the band in some special k-points that is in a small range is abnormal. Almost every band in the same range has very low values,which are much lower than the energy of nearby k-points. There is something wrong with it. The process I calculated the band is as follows.
        create case.klist_band file
        x lapw1 -c -band
        x lapwso -c
        edit case.insp
        x spaghetti -so
I have appended the values of a certain band in the case.spaghetti_ene:

   0.00000   0.00000   0.00000   0.50572   0.57603
The strange is that if not concluding the spin-orbit coupling in spaghetti, that is "x spaghetti",then the band looks normal.
   Whether is it concerned with the E-parameter in case.in1?
   Did anyone else experience similar problems? If necessary,or if anyone is interested in this strange plot, I will append my bandstructure.

     Any suggestions will be much appreciated. Thank you in advance.
