[Pw_forum] strange results in phonon calculation

[Reza Ebraahimi]

Hi
Trying to run phonon calculation at Gamma point for my case, the code gives the following result for some of the modes:      

     omega( 1) =*************** [THz] =*************** [cm-1]
     omega( 2) =*************** [THz] =*************** [cm-1]
     omega( 3) =*************** [THz] =*************** [cm-1]

What does these mean? How should i fix this?
Thanx
