Dear Experts,
I would like to know that what point should be given in the file qpath.dat( filqf='qpath.dat') and how can we get those points?Will it be given in ph.out/matdyn.out file?

Thanks and regards,

Hello,

Those are the fine q-points you want to look at.

Typically you want to use points along high symmetry lines to show properties along the Brillouin-Zone.

Dear Dr. Samuel Ponc ,
As I understand that I can generate the high symmetry BZ k point using wannier90 perl script which should be provided in filkf='kpath.dat' but how can I get the BZ fine q point for phonons?Is there any process for obtaining this?

Thanks and regards,
Anindya Bose

Hello,

The BZ is the same for electron and phonon. Therefore you can use the same path:

filqf = 'kpath.dat'

Best,
Samuel
