Thanks for your quick reply. But i still have doubts on my third question. It's more of a programming question which cannot be found in journal papers.
" iii) In specifying the k-space coordinates to obtain frequencies at a point in the file "*.matdyn.in", what are the units for the co-ordinates? are they just (2*pi/alat) or crystal (in terms of reciprocal lattice vectors)? "
Also do you have experience on graphene?
