Constraint generator

Question on using HydrogenBondConstraintGenerator

The score function I am using is ref2015.wts. It is said that to apply constraint properly, the scorefunction being used needs to have a non-zero weight for the appropriate constraint score term. Does that mean I need to add coorndinate_constraint, atom_pair_constraint or/and angel_constraint into ref2015?

If I want to apply for constraint while docking, but want the original score (without constraint) to be displayed. Do I set mover like this?

<Add mover="add_csts" />
    docking mover here
<Add mover="rm_csts" />

<Add mover="add_scores"/>

Thanks!
