Visualising complex similarity relationships among species

We present the Aequatus, a web-based tool with novel rendering approaches to visualise homologous, orthologous and paralogous gene structures among differing species or subtypes of a common species. The Aequatus utilises web technologies to provide a fast and intuitive browsing experience over complex comparative data. The Aequatus processes and visualises data directly from the Ensembl Compara and Ensembl Core schema databases by using precalculated genomic alignments from Ensembl Compara and relating them to Ensembl Core to gather genomic feature information, visualising phylogenetic and structural relationships among them via CIGAR strings. Whilst applicable to species with high-quality gold-standard reference genomes such as human or mouse, the Aequatus was designed with large fragmented genome references in mind,  e.g. polyploid plants. The ultimate goal of the Aequatus is to provide a unique and informative way to render and explore complex relationships between genes from various species.
