[Pw_forum] How to ignore small negative phonon frequency

[Subhodip Chatterjee]

Dear Artur,

I've solved my problem by changing the negative frequency value to a small
positive number in the file ..../elph_dir/elph.inp_lambda.1 (I got negative
frequency at the first q - point).

Best regards,
Subhodip
