    <p>Dear Paolo, <br>
    </p>
    <p>Thank you for your answer, I would have two more questions
      concerning the projections written in the xml file. <br>
    </p>
    <p>First, even if they are not symmetrized, could I still use the
      square of their norm to plot the fatbands ? <br>
    </p>
    <p>Second, I am interested in doing some rotations between the
      projections in order to see the projection on an effective state
      (namely the Jeff spin orbit states in the TP approximation). But
      when I do so, I find that the results are not what I expect them
      to be. I am award that some codes add or remove a phase factor
      from the projections, and I was wondering if maybe the projections
      from QuantumEspresso were doing the same thing. <br>
    </p>
    <p><br>
    </p>
    <p>Best regards,</p>
    <p>Léo Gaspard</p>

                  QuantumEspresso users and developers,<br>
                  <br>
                  <br>
                  I am trying to parse the atomic_proj.xml file in order
                  to get the <br>
                  projections of the wavefunction on the atomic
                  orbitals. I then computed <br>
                  the weight and compared it to the one reported in the
                  <br>
                  'proj.dat.projwfc_up' file generated by projwfc.x (QE
                  version 6.8).<br>
                  <br>
                  For some projections it worked very well, but for
                  other it did not and <br>
                  the weight was very different.<br>
                  <br>
                  As an example, the projection on the 3rd atomic
                  wavefunction for the 1st <br>
                  k-point and 12th band is -0.100392648675825
                  -0.08369317912931304i , <br>
                  which gives a weight of ~0.0171 whereas in the
                  'proj.dat.projwfc_up' <br>
                  file, the weight written is 0.2336877541.<br>
                  <br>
                  <br>
                  Is there any explanation as to why these two values
                  are not the same in <br>
                  both files ?<br>
