If you have the Energy versus volume data for your crystal you can euse
the gibbs2 free code to do all the analysis. You can learn about the
method in

MA Blanco, E francisco and V. Luaña, Comput. Phys. Commun. 158 (2004) 57--72
<http://dx.doi.org/10.1016/j.comphy.2003.12.001>

an improved version of the code was described in

A. Otero-de-la-Roza and V. Luaña, Comput. Phys. Commun. 182 (2011)
1708--1720; 2232--2248
doi:<10.1016/j.cpc.2011.04.016>
doi:<10.1016/j.cpc.2011.05.009>

The code is maintained and you can get the last version and a detailed
manual from
