[gmx-users] Umbrella Sampling for a single molecule

[Sai Pooja]

Hi,

I am interested in carrying out umbrella sampling for a protein in explicit
solvent with the charmm forcefield. I want to impose a harmonic potential in
the dihedral space of only some specific atoms in the protein molecule. I am
having trouble figuring out a way to apply this using gromacs. Can I get
some help on this?

Thanks
Pooja

p.s. I have seen the tutorial on US by Justin but I am not sure if that is
applicable to a single molecule when the purpose is to obtain the
free-energy function associated with the transition in dihedral angles
of specific some atoms in a protein molecule
