Figure 4

An alignment of three genomes with eleven blocks in all four graph representations. The example covers multiple non-colinear events: Blocks A, E, I, K are conserved in all three genomes without large structural changes. Blocks B, C, and D, as well as G, and H appear in different orders and orientations. Block F is missing in the red genome and J occurs twice. Colors denote the three genomes. In the alignment graph, dashed edges indicate the alignment of a segment with its reverse complement. We consider the information provided by line styles not to be part of the graph structures. In the Enredo graph, components connected by adjacency edges are shaded in gray. For the cactus graph, the figure additionally shows a precursor. Furthermore, enlarged vertices for the precursor and the final cactus graph show adjacencies in vertices.
