Multidimensional whole genome synteny

A popular means to compare whole genomes is the use of Syntenic dotplots. These dotplots reveal regions of the genomes that are related through common ancestry -- either through the divergence of lineages/species or through intra-genomic duplications. CoGe makes the generation of these available through its tool SynMap as well as providing the means to add additional information about the divergence age of syntenic gene pairs to the dots in the dotplot.
