[QE-users] ipol is cartesian or crystal coordinates?

[Gerson J Ferreira]

Dear QE users,

The comments in the code compute_ppsi.f90 state that ipol=(1,2,3) refer 
to the Cartesian coordinates, and this seems compatible with the 
comments in commutator_Hx_psi.f90. However, after checking the output of 
the compute_ppsi.f90 code, it seems to me that it refers to the crystal 
coordinates (a1, a2, a3). I'm running these tests in graphene.

Does anyone know if there's some sort of confusion between coordinates here?

Best regards,
