Hi.
How to tell phenix.refine to leave residue X during refinement?

I already tried in the .eff

>>>
strategy = *individual_sites *individual_sites_real_space rigid_body \
               *individual_adp group_adp tls *occupancies group_anomalous
    sites {
      individual = not (chain A and resid 97)

<<<

But resid 97 is being moved to another position.

I am using phenix.refine_1.10.1-2155

Thanks
