Hi Smith, Range is the distance cutoff used when you click the “Near” or “Contacts” button, as explained in the Help: "The following options depend on which of the atoms within a chain are selected: • Near expands the selection to include additional atoms within Range Å of the original selection • Contacts changes the selection to include the atoms in the initially unselected set within Range Å of the original selection, and the atoms in the original selection within Range Å of the initially unselected set” You can see the Help by clicking the Help button on the dialog, or by viewing the copy at our website (search for “Range” in the page): <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/multiscale/framemulti.html> Best, Elaine ---------- Elaine C.
