I've done that using the current latest data from May 2011, so one year newer than the current default public Blast2GO database provided by the Blast2GO developers (dated May 2011). This requires downloaded some large data files and importing them into a MySQL database, and that took about 24 hours to process in all. The last step is done via their Java tool and took most of the time. For more details, see: http://blast2go.org/localgodb However, the end result is worth the effort as running Blast2GO is now much much faster. I need to try it on some larger files, but we're talking at least an order of magnitude quicker, maybe two. > The input to the tool is a BLAST XML file, specifically blasting > against a protein database like NR (so blastp or blastx, not blastn > etc).

Now that I have a local Blast2GO database, I'll be able to try out b2g4pipe on some bigger XML files (without having to wait ages). > Right now the only output is a tabular three column *.annot file, > which can be loaded into the Blast2GO GUI.

I've submitted the initial version to the Galaxy Tool Shed now, but would still welcome feedback and would even consider non-backwards compatible changes in the short term.
