News/New WebApollo Release (2013/11/22)

Jump to: navigation, search

There is a new release of WebApollo available from the WebApollo release website. The updated server setup instructions are available on the WebApollo Installation page, and the WebApollo user guide has been updated accordingly.

If you currently have WebApollo instances up, please make sure to read the updated server setup instructions as some of the configuration files have changed. Since we now support multiple annotation types, you might want to upgrade your existing data stores to change transcripts to mRNAs (the only supported transcript type in previous versions). See the instructions on upgrading your data store.

You can try the public demo at

Summary of changes:

  • using JBrowse 1.10.9 release
  • new hybrid store (memory/disk) should use much less memory than the pure memory store (with a small degrade in performance) - useful for genomes with many annotations (you can configure which one to use as best fits your needs)
  • viewing of annotation info editor for users without write privilege (cannot modify the data)
  • FASTA data adapter
  • different annotation info editor configurations for different annotation types
  • database/history merger tool (command line)
  • data adapters now use iterators when exporting data (improves memory footprint)
  • add a configurable option for dumping owner and other meta-data to the GFF3 adapter
  • undoing an "add_feature/add_transcript" operation will now warn the user that proceed will delete the feature
  • data adapter grouping (see FASTA adapter)
  • adding/updating PubMed ID will now show the publication title for confirmation
  • improved
  • adding of different annotation types (gene, pseudogene, tRNA, snRNA, snoRNA, ncRNA, rRNA, miRNA, repeat_region, transposable_element)
  • adding GO terms now supports searching/autocompletion
  • annotation info editor now requests data from the server in batch mode (should improve speed)


  • Chado featureprop writeback for generic attributes
  • now properly loads status attributes
  • attributes being lost after undo/redo
  • redo of a merge_transcript operation after deleting one of the transcripts *should* work now
  • properly handle dragged transcripts that contain UTR elements
  • compressed data sent to the client no longer causes the client to hang when there are too many annotations
  • rewrote much of the split_transcript operation to better handle gene splitting
