Dear Stefano and all, I am sorry that I couldn't make my question clear.
Maybe someone who trys to read the small code called 'fqha' in the pwtools directory would know what I am trying to elaborate. I have no idea who wrote it but I think it does a similar work (that is, given a single phonon dos, calculate F at different T). The author must have some reasons in mind for doing this! W.
