[QE-users] help for "ATOMIC_POSITIONS (crystal_sg)"

[Zeli Xu]

Dear QE users and developers,
  I am using the tag of "ATOMIC_POSITIONS (crystal_sg)" in cubic perovskite system. But the output is always wrong. So I put out my Input file and output here. Could you please give me some information or help?
