[Wien] Antiferromagnetic calculation

[marziye foroughpour]

Dear Wien2k user's

 I'm using the Wien2k_5 version compiled with gfortran. I'd like to
know about the Anfinput,  for example I made non-spinpolarized by
setting equal numbers of up and down electron but I was stoped with
this error" afm needs input" and  the Case.struct supergroup  file was
empety with zero size, and I faced with the following massage

14, 'CaseAFM.outputafminput',  'unknown','formatted', 0
15, 'CaseAFM.inclmcopy_st',    'unknown','formatted', 0
16,'CaseAFM.clmup',            'old',    'formatted', 0
17,'CaseAFM.clmdn',            'old',    'formatted', 0
20,'CaseAFM.struct',           'old',    'formatted', 0
21,'Case.struct_supergroup','unknown','formatted', 0

What can I do?
please help me
Regards
