GenSAS: Genome Sequence Annotation Server, a Tool for Online Annotation and Curation

GenSAS  is a Web-based Genome Sequence Annotation Server that provides a one-stop website with a single graphical interface for running multiple structural and functional annotation tools, enabling visualization and manual curation of genome sequences. Users can upload sequences into their account and run gene prediction programs, protein homology searches, map ESTs, identify repeats, ORFs and SSRs with custom parameter settings. Each analysis is displayed on separate tracks of the graphical interface with custom editabe tracks to select final annotation of features and create gff3 files for upload to genome browsers such as GBrowse. Additional programs can be easily added using this Drupal based software. Further development plans are discussed.
