Re: AMBER: TI-FEP : strange result for different clambda values

Hi Biswa,

from my experience with TI this is not an error but to be expected. The
mixing function at lambda -> 1 scales your dv/dl to a small value when k=6
is used. Obviously this is not the best sampling you could wish, because
your result mostly depends on the first 3-4 windows, but this seems to be
the price for avoiding the origin singularity effect. In my opinion you
could try using a smaller k (say 4), use more windows at small lambdas or
live with your results as they are.
