In parallel with the redevelopment of the underlying web-code, the website has been redesigned to improve navigability and discoverability (Figure 1). The new design organizes different views into four classes: Location, Gene, Transcript and Variation, which can be easily navigated between through tabs at the top of each web page. The location class includes views of the genome sequence at a range of resolutions and genome sequence based comparative views (Figure 1A). Gene based views include textual information about the gene, views of its local genomic environment, views of the gene in the context of its orthologs and paralog relationships with other genomes in the Ensembl system and views of sequence variation within that population (Figure 1B). Transcript based views are similar to the gene based ones, but focus around individual transcript structures with more detail (Figure 1C). Variation based views display information focused around individual SNPs (data not shown). Information presented in a single view in previous versions of Ensembl is now presented as separate smaller views in the new design. The relationship between these new views is clearly
