Dinesh, Please send questions such as these to the galaxy-user mailing list (which I've cc'd). You can find the 'Extract Genomic DNA' tool under the 'Fetch Sequences' menu. You may also want to use tool search ('Options -> Show Tool Search'). Thanks, J. On Wed, Mar 2, 2011 at 2:31 PM, <dinesh@gwu.edu> wrote:

Hi Jeremy, You have asked to extract only the exons using the 'Extract Features' tool but all I see here in my developer version under 'Extract Features' is 'Gene BED To Exon/Intron/Codon BED expander'. But the cufflinks files is a gtf file... I have tried to use the above tool but it returns an empty file. Do I need to convert my gtf to bed and then extract the exons and then use the 'Extract Genomic DNA' tool?

Thank You Dinesh Cyanam George Washington University
