Dear all wien users

I have costructed the 2x2x2 super struct file of GaN fom original GaN 
struct file in wz phase by executing 'x supercell' as bellow:

But i don't know what should i do for calculating band structure of Al(x)
Ga(1-x)N alloy with an arbitrary x,for example replacing one Ga with Al 
atom,....what is the key point in replacing of atoms.please if possible 
explain it for  me so clear,because i am begginer. 
Thank you very much in advance.
best regards,
