Hello Di, Both Bowtie and Tophat will map sequences, with Tophat being preferred for RNA-seq data. If you wish to do downstream analysis, then using the Cuff* tools would be the next steps. Each of these tools has an associated help description that explains the inputs/outputs. Thanks for using Galaxy, Jen Galaxy team ps. Please send all questions directly to the mailing lists unless they contain private data/links. On 9/1/11 10:45 AM, Di Nguyen wrote:

Hi Jen,

Thank you very much. I already used Galaxy to prepare the mapping by bowtie for solid. I saw the tophat for solid on the test server and will try it. Do I need to run cufflink after that?

Please accept my utmost appreciation!

Di
