Dear QE  Friends

i did some calculations on phonon dispersion spectrum for tio2. while i was
gone through q2r.out file i noticed that
*reading force constants from file rutile.dynG1 *sentence and gone back to
rutile.dynG1 file. but i found it is doubt to understand without any basic
idea about it. i found some queries, pointed out below, but i need
something more than this about the structure of the file. meaning of each
and every letters.
