Dear all, I have performed phonon calculation using the ph.x executable using a 3x3x2 q-point grid. I would like to get all the 18 dynamical matrix files required by an external code (phq) to obtain the high-temperature phonon dispersion. QE outputs fewer dynamical matrix files (8) than this number because it is greatly reduced by symmetry. I have turned off symmetry in my SCF input file, but I have only obtained 10 dynamical matrix files, an improvement by 2. How can I use the q2qstar.x executable provided in the QE package to obtain all the complete q-points from the reduced number of q-points? Or is there another way to get the complete files for all the q-points? Any help with this would be much appreciated. Best regards, Bill.
