Dear Prof. Kokalj Maybe this question bored you, but it is important for me. Sorry for any inconvenience.
Would you please give me more information that how to recognize the difference in the lattice definition. If I am right in both softwares (QE and MS) A=B<C. So, how did you recognize the difference?

I checked the positions that I gathered from MS Visualizer to prepare ibrav=7 input. Don't know what is MS Visualizer. Anyway I took a closer look and realized that the problem is the lattice definition, which is different in the two cases (MS Visualizer vs QE). All you need to do is to swap the columns, i.e., this will work for ibrav=7: ATOMIC_POSITIONS crystal ? Ba? ? 0.00000? ? 0.00000???0.00000 ? As? ? 0.00000? ? 0.34710???0.34710 ?
