[DI] Analysis of thermal denaturation curves for RNA?

["BarryHenderson"barry at aars.mit.edu]

Hi-
I need to extract enthalpy, entropy and free energy values from 
thermal denaturation curves of small RNAs.  The melts were 
generated on a Cary 3 but the software that comes along with the 
instrument is marginal at best for conducting this type of 
analysis.

Is there any software available that will assist me in this type 
of analysis.  

Thanks,

Barry
