Hi Andrew,

You also might be able to use the knownCanonical table instead of 
knownGene to get around this problem. The knownCanonical table contains 
a single transcript for each cluster of transcripts. (The entire list of 
transcripts in each cluster is in the knownIsoforms table.) The only 
problem with this approach is that you will lose some of the options for 
including or excluding parts of genes (introns, exons, UTRs, etc.) on 
the sequence retrieval options page. If you need a different solution, 
please feel free to write back to this list, and we will try to help you 
find another way to go about the problem.

Please let us know if you have any additional questions: [email protected]
