Hi,
my name is Kasra and I am using the 2020.4 Gromacs version to simulate peptides. I decided to use charmm36-Aug2019 as a forcefield. I do not know which constraints(H_bonds or all_bonds) I should choose for my simulations. I want to know if the charmm36-Aug2019 is parameterized for H_bonds or all_bonds and if there is any solid reference for that.
