[Wien] Error while doing AFM calculation

No, your struct file is certainly not correct.

 From the header I can see you want to do   NaYbO2

So look into your struct file:

I see 4 atoms, but a stoichiometry of   Na Yb4 O2  ???

Of course, also your RMTs are completely unphysical and the atoms are 
much too close.

If one removes the 3rd atom (Y2 with 3 equ. atoms), the structure might 
be ok ?   However, with one Y atom/cell, you cannot make a AFM 
structure, only a FM one. You need to know how the AFM structure is and 
then make a corresponding supercell.
