UniprotParser

Dear all,

I am having issues with the BioJava UniProt parser as detailed below:

Code:

BufferedReader br = new BufferedReader(new FileReader( files[index]));
Namespace ns = RichObjectFactory.getDefaultNamespace();
RichSequenceIterator iterator = RichSequence.IOTools.readUniProt(br, ns);
while(iterator.hasNext())
{
try
               {
RichSequence rs=iterator.nextRichSequence();
}

              catch (NoSuchElementException e)
               {

}
               catch (BioException e)
               {
             e.printStackTrace();
}




The file I am using is downloaded from the link:

ftp://ftp.ebi.ac.uk/pub/databases/uniprot/current_release/knowledgebase/taxonomic_divisions/uniprot_sprot_fungi.dat.gz


The problem is that the parser works for a subset of the IDs within the file
and on others throws an exception.

Sample Exception stack trace:

An example of an Id that worked is:

ZYM1_SCHPO

while an ID that didn't work is:

ZUO1_YEAST

Thanks a lot in advance.

Cheers,
