[Pw_forum] a question about example06

[Yi Kong]

Dear all,
   I have followed the example06 to calculate the phonon spectra of B2
FeAl alloy. The pwscf program run and ended normally, but the two
files named matdyn.out and phdos.out only have the following messages:
%%%%%%%%%%%%%%%%%%%%%%%%%%%
    from matdyn : error #        -1
    non-analytic term for q=0 missing !
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

can anyone give me some advice?

thanks for your attention!

sincerely

Y. Kong
