Example of access to a genome comparison through the MOSAIC Web interface. Twelve Streptococcus pyogenes strains are compared. (a) Main MOSAIC Table describing the general properties of the comparison. A click on the "genome comparison viewer" link gives access to the graphical overview of the five LCBs shown in (b). Selection by clicking on any LCB of the first genome allows the user to zoom in to visualize the backbone/variable segment organization resulting from the alignments, as shown in (c). Backbone regions are shown as grey bars, and variable segments as green bars; genome annotations are superimposed (genes in blue, tRNAs in red). From the main Table (a), access to browse Backbones, Intervals, or Variable Segments [as shown in (d)], is provided.
