Dear Naum: You have repetition because of multiple splice variants. There are several options for solving this problem. Option 1 | Merging Intervals ============================ Use Merge tool in "Operate on Genomic Intervals->Merge". This tool will merge all overlapping intervals into a single one. Option 2 | Clustering Intervals =============================== Cluster tool (in "Operate on Genomic Intervals->Cluster") will find overlapping intervals and will allow you to select the largest. To do so, set tool's options to: - "max distance between intervals" to 0 - "min number of intervals per cluster" to 1 - "return type" to "Find the largest interval in each cluster" Let me know if this helps. anton galaxy team On May 1, 2008, at 9:11 AM, Naum Gershenzon wrote:

Dear Sir/Madam,

I figured out how to retrieve all conserved human 3'UTR sequences from Table Browser, however they came with multiple repetition (up to 5 times). So my question is “How can I filter these data in order to have all conserved human 3'UTR sequences WITHOUT DUPLICATION THE SAME SEQUEMCES MULTIPLE TIMES?”

Sincerely

Naum Gershenzon
