Experience is what you get when you don't get what you

Dear all,
Im using TI within sander in order to compute the free
energy between two enantiomeric complexes, via an
intermediate molecule that is transformed into R or S by
mutation of the apropriate group into dummy atoms.
Im using 12 points for Gaussian Quadrature, the same
points recomended in the manual, to perform data
collection for <dV_dL>. I also set klambda=6 and use 20 ps
for equilibration period and 30 ps for collect averages.
When I look at the results of dV_dL for the fisrt 5 points
the behavior is good, having relatively small fluctuation
dor dV_dL, but for the last points I have very larges
fluctuations for <dV_dL>.
My question is: How can I reduce the large fluctuation for
the last points? Should I use more equilibration time? Or
changing the value of klambda to 4 or 5?
Thanks to all in advance.
Regards
Nelson Fonseca
