[QE-users] Oxygen missing in CoFe2O4 input file

[hamed asadi]

Dear users; 
I have faced a tricky problem to construction of CoFe2O4 input file, in the following input, When I open the structure with Xcrysden, there are no oxygen in it. 
I'll appreciate any helps in this problem. Indeed, if anyone has the correct structure, I'm grateful to give it to me.
