QuartetS-DB Web interface for “Orthologous Groups”. (a) The interface allows users to query and obtain a list (through “List View”) of orthologous groups. (b) The “Tabular View” of multiple orthologous groups indicates whether a group contains an orthologous protein for a given species. (c) Detailed information about an orthologous group (e.g., QTS_4), including the orthologous proteins that are contained in the group. (d) Display of a pre-computed gene tree for an orthologous group that contains four or more species. Detailed step-by-step instructions for this application can be found within the QuartetS-DB Web site under “User’s Guide”.
