[Biojava-l] Any memory-optimised blast parser available ?

[Benoit VARVENNE]

Hello,

I'm trying to parse blast result files from a remote blast on NCBI
databases.
In order to do so, i'm using biojava XML parser like this :

-----------
      InputStream is = new FileInputStream(blastFile);
      BlastXMLParserFacade parser = new BlastXMLParserFacade();
      SeqSimilarityAdapter adapter = new SeqSimilarityAdapter();

      parser.setContentHandler(adapter);

      List results = new ArrayList();

      SearchContentHandler builder = new BlastLikeSearchBuilder(results,
          new DummySequenceDB("queries"), new
DummySequenceDBInstallation());

      adapter.setSearchContentHandler(builder);

// Here is the method that throws 'OutOfMemoryException'
      parser.parse(new InputSource(is));
-----------

While blasting a genomic sequence (i've tried with 50Kb long sequences max),
I've got an OutOfMemory exception.

Does anyone know a way to resolve this ? (this aim is not to dividde my
genomic locus in too many parts, 50Kb is a quarter of my genomic...)

Thanks,
Regards,

Benoit
