The Graph Rider: a graphical interface to display the query results in a graph form. By selecting a line in the Table Rider (Figure 6), the user can display the actual sub-graph associated to it. This snapshot shows an example of result sub-graph corresponding to the Query Q7 (Table 1 [see Additional file 1] and Figure 5). The edge linking the two H. pylori Polypeptides corresponds to a physical interaction (HPIW). The red crosshair on the top-right of some vertices denotes that they are linked to some others that are not currently shown. These vertices may therefore be further expanded to gain more information about the full data graph. In this example, this operation has been performed on vertices holA and holB (from E. coli) in order to display the corresponding Polypeptides (DNA polymerase III) that were not part of the query (see Figure 5).
