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