[Biojava-l] parse (recent) blast output

[Dominique Vlieghe]

Hello fellow biojova'ers

I need, as every bioinformatician who uses java, a blast parser. I tried 
biojova's blastparser (from the cookbook), but recent blast outputs 
(2.2.10-11) are not supported. When I use the lazy method, I get a 
NullPointerException. So my questions are:

1) Has someone of you already succeeded in parsing these recent outputs?
2) Does anyone know why these outputs give me the exception? Has the 
output changed that much going from 2.2.3 to 2.2.10?
3) Would the software tweaks be difficult to implement? I have seen in 
the mailing list archives that some time ago there was a call to 
centralise the biojava parseblast enhancement efforts.  What is the 
status on that? I would like to contribute in (re)writing a blast 
parser, but only if it would serve the general community, so the biojava 
route would be preferred. But since I have outgrown the java newbie 
status only just and I'm totally new to biojava, any advice would be 
appreciated.

Cheers,

Dominique
