Dear Mr. Eli<br />
<br />
You can use F_QHA.x (or fqha.x, as per your Quantum ESPRESSO distribution). It calculates the specific heat using Quasi-Harmonic Approximation (QHA). <br />
The output file is pretty much self-explanatory.<br />
<br />
About QHA you can get more information from the following reference,<br />
<br />
S. Baroni, P. Giannozzi, and Eyvaz Isaev "Density-Functional Perturbation Theory for Quasi-Harmonic Calculations,"Reviews in Mineralogy and Geochemistry 2010 71: 39-57.<br />

<br />
I have attempted to calculate the specific heat from phonon dos as an input.<br />
how do i calculate C-v with out deby model? <br />
