I've been exploring the problems and limits of Ragbag-based DAS service and have tried to see the feasibility of serving real-life data thru' Dazzle/RagbagDataSource and getting some source to work on a viewer. I've finally managed to get a DAS server based on Dazzle serving the Berkeley Drosophila Genome Project GAME-XML files with my RagbagDataSource object. That's roughly 120 Mbases of sequence + annotations I think. The shebang is running on a small machine: Cyrix PR333 (250 Mhz real clock rate) with 256MB RAM. Don't expect blistering performance! Since the system uses lazy instantiation, there will be a brief pause whenever a component boundary is crossed (roughly every 300 kb) The features constitute a subset of the full annotations but will be extended as I improve GAME support in my browser. The server will be up and down over the next few weeks as I work on improving Ragbag for use as a DataSource but it may prove useful to some as another test DAS server dataset. I've prepared a standalone viewer using some of the newer Renderer classes in biojava in it too. (I hope I assembled it right!). It will be rather slow because it's trying to do too much, like compute stops and frames for the six frame renderers from only transcript data (no CDS data). You can wget that from:- http://www.huen.org.uk/david/viewer.jar for a short time but go easy on it - I don't want my ISP going ballistic on me!
