>From the q2r.f90 file:
!     fildyn     :  input file name (character, must be specified)
  !                   "fildyn"0 contains information on the q-point grid
  !                   "fildyn"1-N contain force constants C_n = C(q_n)
  !                   for n=1,...N, where N is the number of q-points
  !                   in the irreducible brillouin zone
  !                   Normally this should be the same as specified
  !                   on input to the phonon code
  !                   In the non collinear/spin-orbit case the files 
  !                   produced by ph.x are in .xml format. In this case 
  !                   fildyn is the same as in the phonon code+the .xml 
  !                   extension.

q2r reads the .xml files. You have only to add the .xml extension in the
input fildyn name.

HTH,

Andrea
