      <p>Dear Claudio</p>
      <p>probably your first calculation terminates regularly and, on
        exit, deletes  the .prd files.  You could try to run  the first
        calculation setting last_irrep = 3 and impose an earlier
        termination setting max_seconds to some lapse that it is just
        enough to compute the first 2 irreps. <br>
      </p>
      <p>Other option: try to comment  the call to clean_pw_ph at line
        135 of PHonon/PH/do_phonon, ( keep the label (100) and put there
        a CONTINUE ). Note that in this case the code should work only
        if you are computing phonons at one q point as it the case of
        your input. <br>
