<p>Dear Quantum Espresso users,<br>
</p>
<p><br>
</p>
<p>I am trying to run the ph.x executable using a simple silicon example which I found online. I first perform the scf calculation and save the results and then use the same outdirectory and prefix when running the ph.x code. However, I keep getting the same
error which says:<br>
</p>
<p>'Error in routine image_q_irr (1):<br>
</p>
<p> some images have no rapp'<br>
</p>
<p>I have attached the ph input file.<br>
</p>
<p>I would really appreciate it if someone can help explain to me why this is happening.<br>
</p>
