Please click on the pencil icon next to your BED dataset, and select 'hg18' under the database/build drop-down menu, and hit save. You should then be able to use 'fetch sequences' tool on this dataset successfully.

Hello,

I'm trying to fetch sequences from Hg18 using a 3 column tab-delimited file (chr coord1 coord2), but the pulldown tab "Fetch sequences corresponding to Query" isn't letting me select any file. How do I get this tool to work?

Thanks,
Courtney
