<p><span style="font-size: 12pt;">Dear all,</span><br>
</p>
<p><span><br>
</span></p>
<p><span>I'm using QE-5.2.0 to do the phonon calculation to test some small gas molecules, such as O2, CH4 etc. </span></p>
<p><span>I got a "<span>dynmat.axsf" for O2 with 6 modes shown below. </span></span></p>
<p><span><span>However, when I type "xcrysden --axsf <span>dynmat.axsf" </span>to visualize the vibrational mode, </span></span></p>
<p><span><span>I can't see any movement when I click the <- and -> arrows back and forth.</span></span></p>
<p><span><span>(I do see the arrows of forces when display them.)</span></span></p>
<p><span><span>Is there anything wrong with this axsf file?</span></span></p>
<p><span><span>Or is there any parameter for the dynmat.x to produce specific axsf to animate a certain mode?</span></span></p>
<p><span><span><br>
</span></span></p>
<p><span><span>Thank you,</span></span></p>
<p><span><span>Xu Huang</span></span></p>
