A radius of gyration distance restraint can be turned on here. It will be active throughout the entire protocol, but can be effectively turned off by setting the force constant for a given stage to 0. The radius of gyration should be entered in angstrom. By default it is applied to the entire system, but can be restricted to part of the system using standard CNS atom selections.

For example to limit it to chains B and C define: “(segid B or segid C)”.

To activate this type of restraints set rgrest=true in run.cns and specify the radius of gyration and the selection to which it applies.
