WeGAS: a web-based microbial genome annotation system.

We have developed WeGAS, a Web based microbial Genome Annotation System, which provides features that include gene prediction, homology search, promoter/motif analysis, genome browsing, gene ontology analysis based on the COGs and GO, and metabolic pathway analysis with web-based interfaces. Most raw data and intermediate data from genome projects can be managed with the WeGAS database system, and analysis results, including information on each gene and final genome maps, are provided by its visualization modules. Especially, a pie-view browser displaying circular maps of contigs and a COG-GO combination browser are very helpful for an overview of projects. Major public microbial genome databases can be imported, searched, and browsed through the WeGAS modules. WeGAS is freely accessible via web site http://ns.smallsoft.co.kr:8051.
