The FIG web is a storehouse of knowledge about bioinformatics in general and the NMPDR in particular. The Main web contains the core pages of the NMPDR web site, including the search facilities, the links pages, and introductory information about the NMPDR's purpose and how to use it. The SOP web contains the standard operating procedures used to maintain the NMPDR web site. The SEED viewer is a portal to all of the NMPDR data. This includes public data, such as the Sprout database, private user data uploaded to RAST, and the internal annotation database. The Sprout database is a public, read-only repository of curated NMPDR data. The RAST database contains genomes uploaded by users. Access to genomes is controlled by the users who uploaded them. The MG-RAST database contains meta-genomes uploaded by users. Access to meta-genomes is controlled by the users who uploaded them. The Annotator Seed database contains genomes in the process of being curated. Access is restricted to the NMPDR annotation team. The Annotation Clearinghouse is a public repository of assertions about known features. Registered users can submit new assertions.
