[Pw_forum] problem with phonon calculation

[chaitanya varma]

Dear Sir,I am trying to calculate DOS, pDOS and phonon densities etc of PbTiO3 -(tetragonal structure)SCF, NSCF and BANDS calculations worked out nicely with tetrahedra,but while doing ph.x calculation i am getting the following error

 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     Error in routine phq_setup (1):
     phonon + tetrahedra not implemented
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

     stopping ...
can i know where i am doing wrong.i am attaching the scf.in and phG.in/out files
thanks and regards Chaitanya Varma MAsst ProfessorGITAM UniversityIndia
