First instantaneous, collaborative genomic annotation editor available on the Web.

Apollo is designed to support geographically dispersed researchers, and the work of a distributed community is coordinated through automatic synchronization: all edits in one client are instantly pushed to all other clients, allowing users to see annotation updates from collaborators in real-time during the editing process. There are no installation requirements for Annotators!

Highlighted features

  • Apollo is a plug-in for the JBrowse Genome Viewer.
  • In addition to genes and pseudogenes, users can annotate ncRNAs (snRNA, snoRNA, tRNA, rRNA), miRNAs, repeat regions, and transposable elements; each annotation type has its own configuration of the ‘Information Editor’.
  • History tracking with undo/redo functions is available.
  • Users are able to directly set an annotation to a specific state, choosing from the ‘History’ display.
  • Adding and updating PubMed IDs will prompt users with a publication title to confirm their submission.
  • Gene Ontology (GO) terms are supported and GO ID auto-completion has been incorporated.
  • Users may access a ‘Recent Changes’ page.
  • Help page with Apollo specific content is available.
