I use Burai software. I use CFFs available from two sites 1-<a href="https://materialsproject.org/materials/mp-2/" style="cursor: inherit;">https://materialsproject.org/materials/mp-2/</a> 2-<a href="http://rruff.geo.arizona.edu/AMS/minerals/Palladium" style="cursor: inherit;">http://rruff.geo.arizona.edu/AMS/minerals/Palladium</a>. There are 4 formats <font color="#ff0000">1-computed 2-conventional-3primitive-4-symmetrized</font> for the site <a href="https://materialsproject.org/materials/mp-2/" style="cursor: inherit;">https://materialsproject.org/materials/mp-2/</a>. When I made Supercell for iron, I realized that if you use any Which of the following formats did the number of atoms in Supercell differ from, while copper did not, and all formats gave me a Supercell with the same number of atoms?</div><div>In order to be more confident, I also tried Palladium, which also had the same problem. My question is, which site do you recommend, and also if the second site gives me the correct Sur Sol format?</div><div><br></div><div>I am a beginner in Quantum Espresso software training. Thank you for your answer<br></div><div></div></div></body></html>
