Subject: AMBER: convert one functional group to another with TI

Hi, I am trying to one functional group to another in
water using TI in Amber 8.0. There are two atoms
(hydroxide) disappearing from starting to the end. I
did two simulations with one in vacuum and the other
in water without separating vdw from charges. I got
the following data set that seems very smooth to me.
Does this seem suspicious to anyone too? Thanks.

Eric
