[QE-users] ​EPW error>>kgmap (???)

Hi all,

As Hari Paudyai said, you may have forgotten to run q2r.x to extract the
IFCs.
I still would suggest you check the Acoustic Sum Rules (ASR for short) for
each step of the phonon calculation. I believe it has to be all the same.

Regarding the kgmap part of the calculation, I lost a huge amount of time
to find out what was going on. Finally, I noticed that the symmetry of the
crystal EPW found was different from the SCF and NSCF calculations. Check
the line "Symmetries of crystal:" in the epw output and compare with the
lines just below the line "atomic species   valence    mass
pseudopotential". These latter one will tell you how many "X Sym. Ops. ..."
were found (X is the number of symmetries). They must be the same.

How do I circumvent that? I just put all the atoms in the center of the
Bravais lattice (without dividing them across the primitive cell). I don't
know if matters to use ibrav =0 or not. I used the one that fits my problem.


Hope it helps.

Best regards,

Marcelo Albuquerque
