Julien Michel, David Case and David Mobley,
Thank you all for your suggestions. I am worried that the usual issues with VDW decoupling is not my
only problem however because my RMS fluctuations are so high, for example 133kcal/mol at clambda =
0.91802, 11.4kcal/mol at clambda = 0.5. Also I already have klambda = 6 and I am making atoms
disappear only (not appear). That's why I am sure that I must have made some error in the set up of the
perturbation topology file, although I cannot find it. I would guess that there must be major differences
between my perturbed and unperturbed force fields besides the LJ radii which I intended to perturb.
Does anyone know an easy way to compare the perturbed and unperturbed force fields?
Thanks again,
Holly
