[QE-users] epsilon.x returns infinity and NAN in epsr and epsi

Dear quantum espresso experts,

We are trying to evaluate the dielectric tensor of a 50% Ag 50% Ag alloy
using epsilon.x (eps calculation). We had already relaxed the structure,
calculated scf, nscf, and bands without errors. However, after successfully
ran epsilon.x it keeps returning epsr.dat, epsri.dat files fulled with NaN
and infinity.

We had used options in the nscf calculation nosym = .true.,
noinv = .true. , as well as norm-conserving pseudopotentials for Ag and Au.

Thanks in advance, and looking forward to your answers!!
