[Pw_forum] how to extract data from phonon calculation to plot phonon frequency dispersion curve

[bamidele ibrahim]

Dear all,
 I want to plot phonon dispersion frequency curve. i perform scf and phonon calculation at gamma point(0,0,0), where i have an output file .dynG. Inside this file, there  are some data which i think is to be use to plot the phonon frequency dispersion curve. but to extract these data is a problem. Can anybody help me out? Your assistance will be appreciated.
thanks,
ibrahim
