[Pw_forum] Plotting phonon dispersion

[elchatz at auth.gr]

Hello all,

I am using ph.x to get the phonon frequencies and dynamical matrices  
for an epw.x calculation, however, I would like to plot my phonon  
dispersions from the ph.x calculation for far, as for example is shown  
in

http://epw.org.uk/Documentation/B-dopedDiamond

I am lost as to how I can do that. My ph.x file is as follows,

&inputph
   prefix   = 'Si',
   epsil    = .false.,
   fildyn   = 'diam.dyn',
   ldisp    = .true.
   fildvscf = 'dvscf'
   nq1=6,
   nq2=6,
   nq3=1,
   tr2_ph   =  1.0d-12,
   recover = .true.
  /

Do I need to use q2r.x and matdyn.x to the files for plotting?


Thank you
