[Pw_forum] a few frequencies in PHONON calculation

[Eduardo Menendez]

Hi,
I have one doubt about the PHONON code. Is it possible to compute just a
few phonon frequencies using the PHONON keywords last_irr, ldiag ? For
example, using

last_irr = 10,
  ldiag=.true.,,

may one find the frequencies of just the first irreducible representations ?

Thank you,
