Users can target residue pairs in RRDistMaps for further navigation in Chimera. hinge motion), between unbound and bound proteins through distance patterns. An interactive utility, RRDistMaps, visualizes conformational changes, both local (e.g. We have developed a UCSF Chimera tool, RRDistMaps, to compute such generalized maps in order to analyze pairwise variations in intramolecular contacts. Binary (yes/no) contact maps with a single cutoff distance can be generalized to show continuous distance ranges. Motivation: Contact maps are a convenient method for the structural biologists to identify structural features through two-dimensional simplification.
