<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Dear all QE users,
<div><br>
</div>
<div>I'm using QE to calculate phonon dispersion relations and Phonon DOS. </div>
<div>For phonon DOS, when I use the k-path provided in the tutorial for FCC structure, I obtained a reasonable result.</div>
<div>However when I used the k-path generated by tetra.x, I got a weird phonon dispersion relation. Is that normal?</div>
<div><br>
</div>
<div>Also, I would like to create a ttrinp file for orthorhombic base center lattice which is not provided with the code. Does anyone know where I can find it or provide instruction on how to built it?</div>
<div><br>
</div>
<div>Thank you in advance for your help.</div>
