Overview of GSV Synteny Browser. In this simulated example, users can switch among three pairs of genomic sequences for analysis (i.e., Organism A vs. Organism B; Organism A vs. Organism C; Organism B vs. Organism C). The synteny view of Organism A vs. Organism B is displayed at the center of the browser. Each selected genomic sequence is represented as a black horizontal ruler. Users can zoom in/out, pan left/right or select specific genomic regions for a customized display. Users also have the choice to display the two entire genomic sequences by clicking the button View Entire Genomes. In this example, the conserved genomic regions between Organism A and Organism B are shown in colored blocks. Above the synteny view, three annotation tracks are displayed for Organism A (i.e., the "gene" track in blue arrows representing the predicated genes for each genome, the "expression" track in green bars representing whole genome tiling array hybridization intensity, and the "transposon" track in black boxes representing putative repetitive elements). Below the synteny view, only the "gene" and "expression" tracks are displayed for Organism B. Note that the "transposon" track is turned off for Organism B, but can be turned on through Annotation tracks display on/off from the control panel. Additional control panel at bottom of the display (not shown here, see Additional file 1, Figure S7) allows users to export their customized figures in the png format. See text for additional description of the browser's functionality.
