can anyone tell me how to find the conformational free energy?
i have the one peptide which have 12 amino residue.
i was run the simulation. and found the g_energy from trajectory file.
i have potential energy.
now i want to find the conformational free energy and entropy and enthalpy.

any one know plz help me.
thanks...

You can estimate the conformational entropy using g_covar and g_anaeig (Quasi-harmonic and Schlitter). You probably need to do some literature search as well, these are difficult topics.
