[Pw_forum] overlap of atoms

[Payam Norouzzadeh]

Thank you Prof.Baroni for your reply.

Actually I used both Xcrysden and Jmol to visualize the structure. The
result was good and also I compared the result with
available pictures of that structure in literature.One problem is that the
positions like  0 0 0 and 0.5 0.5 0.5 are considered overlapped
in this structure by QE probably because of symmetry.

Best regards,Payam Norouzzadeh
