Provides a feature-rich set of comparative genomics tools for inspection of multiple genome structures, mining of orthologous gene families and identification of potential vaccine candidates. The Sybil suite of feature-rich web tools allows users to search and visualize several genomes based on clusters of orthologous genes. The views in Sybil are interactive allowing users to click on each drawn feature to retrieve more detailed information. Navigation between views is supported and provides Sybil with the unique ability to explore from the whole genome level to the protein and nucleotide multiple sequence alignment level without leaving the application. Export of tab-delimited tables, sequence data, and SVG and PDF publication-quality figures is possible from many of the views.
