Hi everyone!<div>I am using CP2K for running metadynamics simulations. I used the graph.popt tool for obtaining the free energy of my system, but actually I can't understand how it is calculated. I read that the final energy results are in hartree but if I convert them in eV they do not make any sense in terms of order of magnitude, even if the obtained curve is in agreement with what I expected. I know that the free energy should be calculated considering the probability distribution of the CVs but if I try to reconstruct the curve in this way, I don't obtain the same results obtained by exploiting the graph.popt tool. I also tried to use the python script found at https://www.cp2k.org/exercises:2021_uzh_acpc2:ex03 and the range of free energy is reasonable in this case, but completely different respect to what obtained by using graph.popt, so I think that I'm not understanding what is printed by this program.</div><div>Can you help me to solve this question?</div><div><br></div><div>Kind regards,</div><div>Laura</div><div><br></div>
