Hi,
This is regarding the energygroups that one can use in the mdp
file for tracking energy. Are these the groups defined in the
index file?
Yes, the groups are defined there (or created by default if an
index file is not supplied) and specified as energy groups in the
.mdp file.
I want to know if I can define a subset of atoms in the index
file and track its energy.
Yes. Whether it means anything is another matter.
Well the idea is to modify the hamiltonian for only a subset of atoms
and apply hamiltonian replica exchange. I was hoping defining energy
group could be a good way to apply this(obv it would requires other
changes too).
Describing the overall objective is usually a good idea. Sometimes one's
candidate for a solution is not best and someone else knows it :-) Here,
energy groups are the only reasonable solution.
