[Pw_forum] Phonon calculations - separating modes

[Sheena Shah]

Dear all

I am trying to run a phonon calculation (ph.x) by splitting up the modes into different calculations using start_irr and last_irr.  I am having troubles in the recombination process to create a phonon dispersion.  The frequencies are correct but I am unable to use the potential file (dv1) for  doing electron phonon coupling calculations.  Can someone please help me with this?

Many thanks
