Please update the code (I hope even the new version WIEN2k_05/1 will be 
ready soon). AFMINPUT has been replaced by a new version 8 month ago. It
will not ask these questions anymore, instead it works with symmetry and
grouptheory. 
It is preferable to supply a   struct  file of the nonmagnetic superstructure,
and afminput does all the rest automatically (in some cases or without
this struct file, you will be required to supply ONE symmetry operation,
which transforms these AF-atoms into each other.
