Dear Sir,
         Yes. I considered spin-orbit coupling and for that the dynamical
matrices are written in xml format as mentioned in the program. Later the
problem was solved by adding ".xml" in the dynamical matrix file of the
input.

Previous input for q2r.in was
&input
fildyn='au.dyn', filfrc='au888'

which does not work.
But as I add .xml in the name of fildyn then it works.
&input
fildyn='au.dyn.xml', filfrc='au888

 Anyway thank you for your reply.

  Regards
