[gmx-users] Regarding Free energy (Energy barrier) calculation

[neeru sharma]

Dear Gromacs Users,

Greetings of the day!!

I am simulating a system of Protein-Mg-GTP complex. There are 2 states for
the same, state 1 and state2. The difference lies in the presence of 2
specific H-bonds in the state 2 ,which are absent in state 1.
Now, I need to find the energy barrier that was crossed to reach state 2 (2
H-bonds) from state 1. Can you suggest me some way to find this energy
barrier in gromacs ?

Thanks in anticipation.
