Hey everyone, I am a new galaxy user. I am trying to upload coding exons of specific region from ucsc genome browser but I end up with loading coding exons of all splice variants/isoforms. As a result some exons are repeated many times (depending upon how many isoforms the crossponding gene has) which I don't want. Can somebody help me how can I have a list of coding exons in which each exon is represented only once irrespective of how many splice variants/isoforms the gene has? Thanks a lot [cid:image001.jpg@01CA41C8.B3A28E40] Atteeq Ur Rehman Visiting Fellow National Institute on Deafness and Other Communication Disorders, National Institutes of Health, Room 2A-19, 5 Research court, Rockville, MD, USA, 20850.
