<div dir="ltr">Dear PWscf users and developers,<div><br></div><div>I am currently using Quantum Espresso 5.3.0 to compute a hexagonal system (R-3c, space group 167). I am wondering if space_group and crystal_sg are still implemented in QE? I keep getting an error message like below: </div><br>Error in routine read_cards (4):<br> wrong number of columns in ATOMIC_POSITIONS<div><br></div><div>My input file looks like the following, which I believe (and hope) to be correct. </div><div><br> &system</div><div>....<br> space_group= 167, rhombohedral= .false.<br> ibrav= 4<br> celldm(1)= 8.0 </div><div> celldm(3)= 2.0<br> nat= 30, ntyp= 3<br> ...<br>ATOMIC_POSITIONS {crystal_sg}</div><div> Mg 6b<br> C 6a<br> O 18e 0.30</div><div><br></div><div>(Notice: 18e only needs a parameter x, while 6b and 6a do not need anything) </div><div><br></div><div>I am thus wondering if the Wyckoff position is still implemented in QE? Or perhaps the above input file is indeed not written properly? </div><div><br></div><div>Thank you very much for any answers.</div><div><br></div><div>Best regards,</div><div><br></div><div>Han<br clear="all"><div><br></div>-- <br><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr">===============================<br> Han Hsu (徐翰)<br> Assistant Professor<br> Department of Physics<div> National Central University<br> Taoyuan 32001, Taiwan<br> Email: <a href="mailto:hanhsu@ncu.edu.tw" target="_blank">hanhsu@ncu.edu.tw</a><br> Tel: +886-3-422-7151 ext 65303<br> Fax: +886-3-425-1175<br>===============================</div></div></div></div></div>
