12 How do I calculate the vibrational energy, free energy, entropy, and heat capacity?

Use what='scf_disp'. See example04. These quantities are calculated after the phonon dispersion calculation for the default temperature range (1 K - 800 K) or for the range given in the thermo_pw input. The figure of these quantities is in the file output_therm.ps.g1. Note that they are calculated at the geometry given in the input of pw.x.
