structureViz Plugin Version: 0.9 Release Date: January 25, 2007 Verified to work in 2.4 This plugin links the visualization of biological (and biological relationships expressed as networks) provided by Cytoscape with the visualization and analysis of macromolecular structures and sequences provided by the molecular visualization package: UCSF Chimera. structureViz provides commands to open structures in UCSF Chimera, align open structures using Chimera's Sequence/Structure tools, close structures that are currently open, and exit Chimera. In order to load a structure associated with a node, the Protein Databank (PDB) identifier (or identifiers if there are more than one) must be present as an attribute of that node. Currently, structureViz will look for an attribute named Structure, pdb, or pdbFileName. When a structure is opened, structureViz provides an alternative interface to Chimera: the Cytoscape Molecular Structure Navigator. This interface uses a tree-based paradigm to allow users to select and effect the display of models, chains, and residues, mostly through the use of context menus. Additional commands allow for selection by chemistry (Ligand, Ions, Solvent, Secondary Structure, and in the model context menu, Functional Residues). Users can also take advantage of Chimera's structural alignment capabilities by using the "Align" command. Released by: John "Scooter" Morris, RBVI, UCSF [Web Site and Download]
