[Pw_forum] warning in q2r.x

[Subhradip Ghosh]

I am doing phonon calculations on a L10 structure. The output of q2r.x
produces the following warning:

"fft-check warning: sum of imaginary terms = .2454409E-06"

How serious is this warning and what could be the consequences? Also, what
could be the possible reasons?

Regards,

Subhradip
