</font></div>
<div class=""><font size="4" class="">When using the ph.x code, the output shows the label for the irreducible representation for each mode, such as T_1g or T_1u as done in the divide_class.f90 routine of the PW/src. When putting a list of say 2000 q-points
into matdyn.x, I can get the eigenvectors for each mode. </font></div>
<div class=""><font size="4" class=""><br class="">
</font></div>
<div class=""><font size="4" class="">Is there a tag or a post-processing tool which allows the determination of the irreducible representation label for the modes associated with each of those 2000 q-points? If not, is it possible to extract the table for
irreducible representation for all the modes of a list of q-points in QE?</font></div>
