Transcript of J browse WormBase Workshop International Worm Meeting 2015
- 1. A New Genome Browsing Tool at WormBase Scott Cain [email protected] WormBase Developer GMOD Project Coordinator
- 2. Old Genome Browser (GBrowse) Has been around a LONG TIME (it looks a little like the 90s). Can have issues dealing with newer data types (no support for VCF, BAM can be quite slow). Has reached end of development. Considerable hassle to maintain.
- 3. New Genome Browser (JBrowse) Next Gen genome browser in the GMOD project. Uses JavaScript/AJAX to provide a very interactive, speedy experience. Image rendering takes place in the web browser rather than on a server (speedy for you, smaller servers for us).
- 4. Navigation (show movie)
- 5. Data Manipulation File menu Open (local/remote) Combination Tracks Sequence Search
- 6. Open Supports BAM, BigWig/Bed, Indexed VCF and GFF3 Supports local open, i.e., it will open files without uploading them to a server (so it is FAST) Fetching by URL from web/ftp (so can use Google Drive, DropBox, etc)
- 7. Combination Tracks After selecting Create Combination Track, simply drag the two tracks together that you want to combine. Use set operations to combine (intersection, union, subtraction, etc)
- 8. Sequence Search Create a persistent track that will show you when reference sequence matches a pattern. Can be strand specific Can use regular expressions Can search DNA or translated amino acid sequence
- 9. Other Niceties Pin to top makes a track sticky at the top (wont scroll away) Download track data Create a URL that you can email, post, etc. Full page button removes WormBase header/footer giving you the whole web page for genome browsing.
- 10. Wrap up Much thanks to Ian Holmes (UC Berkeley) and his group, particularly Rob Buels, and Colin Diesh in Chris Elsiks group (U Missouri). Poster 953A (Thursday, 9:00-10:30PM) The new genome browser is available at http://jbrowse.wormbase.org/ (redirects to main WormBase site). I tend to hang out on IRC (##worms and #gmod at freenode.net), and of course you can always send email to [email protected] or me directly at [email protected]. PLEASE feel free to make suggestions for improvements!
