Hi Crystal,
You can exclude any part of your model with a selection like this:
refinement {
refine {
strategy = *individual_sites *individual_sites_real_space rigid_body \
*individual_adp group_adp tls *occupancies group_anomalous
sites {
individual = "not chain B"
torsion_angles = None
rigid_body = None
}
}
}
In this example, I've excluded chain B from individual site
refinement. You can see more selection examples here:

Thanks,
Jeff
