The zone command shows atomic detail and residue labels near a specified single residue of interest. Density-map or other volume data displays can also be restricted to a zone near that residue, and different cutoff distances can be used for the atoms, residue labels, and volume displays:
The cutoff values remain in effect for automatic application with the zone command and/or zone mouse mode until they are explicitly changed or ChimeraX is exited.
The label option indicates whether to show zone residue labels (default true; false removes all residue labels). The ribbons option shows the beyond-zone residues of the same atomic model as a narrow ribbon (default true; false does not modify any existing cartoons).
The zone clear command clears the labels and returns to what was shown before zoning.
