<div>Dear Forum, <br>
</div>
I have run a ph.x calculation for phonon dispersion including spin-orbit coupling using 4x4x4 grid with qe5.4.0. version. At the end of the calculation, I got dyn files in case.dyn.xml format instead of case.dyn. Here I am unable to use this
case.dyn.xml for further running q2r.x and matdyn.x to obtain case.fc and case.freq. Please help me in this regard.<br>
<br>
</div>
thanks in advance,<br>
