Hello, Olga. I'm not certain what format you're using to enter your IDs. If you're using the RefSeq ID (e.g., NM_020706 which is unique), I'm not certain why you would be seeing a disproportionate number of results to IDs. If you're using the gene name (e.g., SCAF4 which has several transcript variants), I can understand why you are seeing a disproportionate number of results to IDs.
If this does not answer the question for you, could you please send the list of IDs that you are using so I can attempt to recreate the problem? Please contact us again at [email protected] if you have any further questions. --- Steve Heitner UCSC Genome Bioinformatics Group -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Olga Müller Sent: Monday, May 14, 2012 1:11 AM To: [email protected] Subject: Re: [Genome] Extract 3' UTR sequence with refSeq Hello Vanessa, I have a question concerning the extract of the 3 UTR sequences with the UCSC-software. I want to get the 3 UTR sequences of some genes. As an input I used the Probe Set IDs (and also once with the Transcript IDs) I got from an Affymetrix expression analysis. When I for example used 200 Transcript IDs as the input, I received UTRs for more than 200 IDs. And there also not 100% homologous with the input-IDs. What could be the reason for that? I pasted the Input data following this link: https://lists.soe.ucsc.edu/pipermail/genome/2011-March/025259.html thank you very much in advance.
