[Pw_forum] How to ignore small negative phonon frequency

[Subhodip Chatterjee]

Dear all,

I'm getting a small negative frequency in my phonon calculation, and
consequently getting NAN for Tc and related quantities while running
lambda.x. I've found a post in the forum (http://www.mail-archive.com/
pw_forum at pwscf.org/msg28237.html) where two probable solutions were
suggested. Can someone please guide me how to proceed? I mean which lines
in which files need to be edited?

Best regards,
Subhodip
