[Wien] Lattic Type for wz structure

[Rezaei Behrooz]

Dear Profe. P.Blaha
Thank you very much for your reply,but I'm surprize because I have read 
from userguide file that 'F' notation is used for 'FCC' structure as a 
lattice type,not for wurtzite(wz)one.So please let me know which should 
I use for lattice type on wz structurer in struct file.where the aoms 
are located at:
Atom 1 : (0,0,0) , (2/3,1/3,u)
Atom 2 : (0,0,u) , (2/3,1/3,1/2+u) 
u=0.375 is the internal structural parameter.
Thank you in advance.
best regards,
