I increased the potential to 2350 instead of 1000 in my md_umbrella.mdp (the other parameters kept unchanged), then the movement of my protein was less than the previous one, which we can see from pullx.xvg (attached). But it still not reach to the designed region. So I am going to increase the

Thank you for your reply, Thomas. Under your explanation, I am well understood of the terms: pull_k and pull_rate. Here I upload both md_umbrella.mdp and md_pulling.mdp. I have to mention that it is coarse gained system with Martini force field. At the same time, i am going to run a simulation

Dear Justin, Based on your questions to my simulation, I posted here yesterday hopefully it was the correct way to reply in this forum. In this morning I got a list of new windows of umbrella sampling, the overlap is sufficient enough, but I saw another problem: In the histogram figure, the b
