Hello,

Thanks for the reply.

I have Delta H = -4002 (calculated through MM-PBSA) and TSTOT = 502 (calculated through NMODE). Will the DeltaG (of binding) be -3500 or -4504?

I mean to ask TSTOT gives (-T delta S)  OR (T delta S). Which one is correct?  Because different  previous references are showing both the ways for NMODE results.

Gut feeling tells me:

T > 0
delta S > 0

and there you go!

Sign must be positive or equal zero :)

But I wish I could see the output of your AMBER job
