[Biojava-l] How to extract chromosome ID from a Transcript?

[Alberto Ambesi]

I can successfully extract Location and Strand features from a 
transcript, but I can't find a way to get the chromosome ID where the 
gene is located. I am using the following code:

         SequenceDB chromosomes =ens.getChromosomes();
         FeatureHolder transcripts = chromosomes.filter(
             new FeatureFilter.ByAnnotation(Ensembl.TRANSCRIPT_GENEID, 
ensID)
         );
         iter= transcripts.features();
         while (iter.hasNext()) {
             StrandedFeature feat = (StrandedFeature)iter.next();
             System.out.println("Strand: \t" + 
feat.getStrand().toString());
             System.out.println("Location: \t" + feat.getLocation());
         }

thanks a lot.
