Hello all,
I have done a TI calculation, but can't find any tutorial or document about
how to interpret the output. Here is how my output file starts

It seems like BOND1 and BOND2 etc. are for the initial and final values of
lambda, respectively. If so, is AVGBOND1+AVGELECT1+AVGVDW1 the total TI
energy for each timestep? then if I sum the total energies of all timesteps
I will get the total TI for the total transition from lambda=0 to lambda=1?
Thanks in advance,
Sadegh
