Dear Hamed,
Your oxygen atoms are positioned more or less exactly on top of the
other atoms, that's why you don't see them.
E.g.
Fe 5.2187500 5.2187500 5.2187500
O 5.1185500 5.3189500 5.3189500
Fe 3.1312500 7.3062500 7.3062500
O 3.0310500 7.2060500 7.4064500

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.
