Have you compared the results of your calculation using the forces at different intervals? e.g. every 1, 10, 50, 100 steps ? As long as you use a not-so-large interval the result should be the same within statistical error. Cheers, Leandro On Mon, Jun 19, 2017 at 7:19 PM, Lutz Maibaum wrote:

I am using “umbrella pulling” to simulate the dissociation of two molecules. I would like to calculate the work W(t) that the harmonic trap has performed on my system up to timestep t, which can be calculated as W(t) = sum_{i=0}^t F_i * v * dt where F_i is the biasing force at timestep i, v is
