[Genome] "_dupX" names for transcript ID duplicates on same chromosomes

[Micha Sammeth]

Hello again,

thank you, Robert for the explanation on the ESTs, I got it clear now.

I have another little problem, hopefully the last one for this project: 
when I download the (hg17) mRNA track, I get conveniently unique 
transcript_id tags - at least on a chromosome level, which is enough 
(e.g., "AK130020" and "AK130020_dup1" on chr1). From which field does 
the table browser retrieve them? It does not seem to be all_mrna.qName, 
nor did I find a field in gbCdnaInfo or other soundy tables that are up 
to 1-2 joins away from all_mrna. I would need these "_dupX" identifiers 
to map back the CDS info I get from hg17.cds to genomic coordinates.

Best thanks, micha.
