[Pw_forum] Question about tetra.x in QHA package

[Sokseiha Muy]

Dear all QE users,

I'm using QE to calculate phonon dispersion relations and Phonon DOS.
For phonon DOS, when I use the k-path provided in the tutorial for FCC structure, I obtained a reasonable result.
However when I used the k-path generated by tetra.x, I got a weird phonon dispersion relation. Is that normal?

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?

Thank you in advance for your help.
