Hi all,

I would like to set a high constraint on one set of atoms with a constant
constraint coefficient throughout my simulation while at the same time
setting a low constraint on a separate set of atoms (a protein backbone)
and relaxing that constraint coefficient gradually to release the protein.

How can I set these two separate constraints?
