"Hello Wei, Thank you for sending more information and sample data. The general query path would be to: 1) bring in the UCSC Genes 3' UTR annotation as a dataset (knownGene -> BED -> 3' UTR Exons -> Galaxy) 2) analyze your data versus these target transcripts by overlap using tools in the group "Operate on Genomic Intervals" You may find it helpful to group transcripts and overlapping samples into gene clusters using the UCSC table knownIsoforms. Hopefully this helps to get you started, Thanks, Jen Galaxy Team On 6/22/10 10:07 AM, Yanwei Tan wrote:

Hi Jen,

I have stimulated sample and control sample, I would like to know if there is 3 UTR, 5 start site variance in the stimulated sample. There is always some interesting info in the 3 UTR. If the length of 3UTR changes under specific biological condition, then it could explain some mechanism, for example some microRNA info.

And so far, I uploaded the bed file to Galaxy, and choose from cdsEnd to txEnd (should be transcript end, right?) which should be 3 UTR info. If this is right, I check by hand every 3UTR of every gene compared with public annotation like UCSC. But this is not a proper way and time-consuming. I do not have bioinfomatics experience, do not know if one can give me some advice how to do this properly.

Many thanks for your help!

Best, Wei

Hi Wei,

Could you explain in more detail the type of analysis that you are interested in doing? Including a few lines of the BED file (5-10) pasted into the reply would be helpful.

Thanks,

Jen Galaxy Tea

Deal all,

I was wondering if anyone know Galaxy can analyze the New 5' start site, 3' end site and long internal coding exons. Because I just try to run Scripture (http://www.broadinstitute.org/software/scripture/Graph%20building) and got the bed file. Can someone give me some hint?

Many thanks in advance! Wei _______________________________________________ galaxy-user mailing list galaxy-user@lists.bx.psu.edu http://lists.bx.psu.edu/listinfo/galaxy-user
