[Biojava-l] SubSequence Help

[Ella Veitch]

Hi guys- new here hope this is the right medium for getting questions  
answered.

I hope someone can shed some light as to what i am doing wrong here
I am trying to extract subsequence data from a RichSequence as follows:

	RichSequenceIterator seqs=RichSequence.IOTools.readFastaDNA(input, ns);
	RichSequence rs=seqs.nextRichSequence();
	
	return RichSequence.Tools.subSequence(rs, startCoord,  
endCoord,rs.getNamespace(),seqName,
				rs.getAccession(), rs.getIdentifier(),  
rs.getVersion(),rs.getSeqVersion());

When I check my result againt the expected i find that for example  
5001-5175 yeilds a sequence located at 10001 and 10175

Any insights as to why?

I hope so

Thanks for your help

Ella
