Basic layout of the plug-in and distinctive features. Plug-in functions are available in the iRefIndex menu (a), the wizard (b), the search area (c), the advanced features area (d), and by right-clicking on any node or edge in the graphical view area (e). Tabs in the Data panel (f) show Node Attributes and Edge Attributes. The user may choose which attributes appear in these panels using the Attribute selector icon (g). Two protein nodes appear as ovals. Each has a distinct amino acid sequence. A multi-graph representation allows multiple edges between these two nodes where each represents source data supporting some relationship between the two. A bipartite representation is used to distinguish n-ary interaction records (hexagons with pink edges) and their members (adjacent nodes) from binary interaction records. The edges selected using the mouse are shown in red and their properties will be visible from the attribute browser.
