[Biojava-l] creating a sequence...

[Jan Würthner]

Hi,

I have written a BlastParser for xml based BLAST results, in order to 
reconstruct SeqSimilaritySearchResult instances from xml files returned by 
the NCBI for BLAST requests.

In constructing the searchresult, I use

SequenceBuilder sb = new SimpleSequenceBuilder();
SeqSimilaritySearchResult result
    = new SimpleSeqSimilaritySearchResult( sb.makeSequence(),
							  new DummySequenceDB("dummy"),
							  searchParameters,
							  hits,
							  new SimpleAnnotation(annotations));
where hits is a List of SeqSimilaritySearchHits and searchParameters and 
annotations are Maps.

The XML file still contains information about the query, like ID and length, 
but not the whole query sequence, e.g.:

  <BlastOutput_query-ID>gi|1698579|gb|U60438.1|MMU60438</BlastOutput_query-ID>
  <BlastOutput_query-def>Mus musculus serum amyloid A protein isoform 2 mRNA, 
complete cds</BlastOutput_query-def>
  <BlastOutput_query-len>576</BlastOutput_query-len>

Here is my question:

How can I adopt this information into the SimpleSeqSimilaritySearchResult? The 
sequence I obtain by

  sb.makeSequence()

of course does not contain anything. Is there a way to construct a sequence by 
the query-ID, query-def and query-len? (Especially the length is something I 
need!)

Thanks in advance
Jan
