Both of these
inputs belong to the 3*3*3 supercell of Fe pure metal (I have prepared the
graphical structure with the common windows based programs. Then I used
"cif" file and copy the 5 digit coordinations to the QE inputs). To prepare these inputs I started with
conventional cell (and not primitive ones). Then I built supercell from it. For
the first input, I take the symmetry of "p1" and didn't change it,
but for the second one I searched for the highest symmetry that the supercell
has. I found that it has 229 (Im-3m) space group which is BCC. Then I rebuilt
it according to this symmetry. 54 atoms reduced to only 4. However, the size of
the cell remained unchanged.</span></div><div class="yiv0656715938MsoNormal" style="color: rgb(0, 0, 0); font-size: 11px; font-family: HelveticaNeue, 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif; background-color: transparent; font-style: normal;"><span lang="EN"><br></span></div><div class="yiv0656715938MsoNormal"><span lang="EN">Please, see the files, and help me for following questions</span></div><div class="yiv0656715938MsoNormal" style="color: rgb(0, 0, 0); font-size: 11px; font-family: HelveticaNeue, 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif; background-color: transparent; font-style: normal;"><span lang="EN">:</span></div><div class="yiv0656715938MsoNormal"><span lang="EN">1- QE contrary to some other codes needs total of atoms in the cell (If I
