Hello,<br>I am using QE (obviously) and xcrysden.<br>I am making the supercells just by:<br><ul><li>making the unit cell</li><li>using xcrysden to modify the small cell by doubling it in different directions</li><li>finding the atom positions one by one <br>
</li><li>making supecell by entering those atomic positions into a new lattice to give exactly the thing that I made with xcrysden.</li></ul>I was wondering whether there is a simple way to double the unit cell in different directions.<br>
Thank you<br>P Shok<br>
