A typical IM Browser window. The panel at the left lists the interaction tables available in the database. New tables added to the database are dynamically added to the list. The main window (right) shows an interaction map with nodes (yellow circles) representing genes or proteins and edges connecting them representing interactions. The edges are colored based on the tables from which the data came, according to the key in the lower left panel; in this case, red edges indicate that the interaction is found in at least two interaction tables. The coloring scheme can be defined by the user as described in the text. Nodes and edges in the graph are both 'clickable' to obtain more information about the gene/proteins or interaction attributes from the data tables, respectively, and to link to outside databases. The graph can be manipulated manually or redrawn based on preset or user-defined parameters.
