Hi, Sorry to bother you. Recently, I have encountered a problem when running free energy calculation of a dna-ligand complex system. The structure start to getting weird when I try to specify the two state (A,B) in the topology file, which is never spotted in the unconstrained MD simulations.
The version I am using is 4.6.7 and the force constant is 1000/nm/rad^2. Could you help me with that?
