search for: excon_start

Hi, I'm heaving difficulties with a dataset containing gene names and positions of those genes. Not such a big problem, but each gene has multiple exons so it's hard to say where de gene starts and where it ends. I want the starting and ending position of each gene in my dataset. Attached is the dataset: http://www.nabble.com/file/p21312449/genlistchrompos.csv genlistchrompos.csv Column
