Hello David, Renaming with incremental numerical sequence (or with sequence), as you did originally with the tool "NGS: QC and manipulation -> FASTX-Toolkit for FASTQ data -> Rename sequences", is the current option. If your or someone else following Q/A on the list develops a tool that offers a partially fixed/partially incremental numerical renaming operation, it would be nice addition to the Tool Shed. Sorry for the delayed reply. To let you know for next time, the best forum for quick data/tool usage questions would be the galaxy-user@bx.psu.edu mailing list. http://galaxyproject.org/wiki/Support#Public_mailing_list_Q_.26_A_discussion... http://galaxyproject.org/wiki/Mailing%20Lists Best wishes for your project, Jen Galaxy team On 9/23/11 10:05 AM, David PANG wrote:

Dear All,

I am new to Galaxy!

When I tried to manipulate mt fasta sequences from RNA-Seq, I just add

...

1, >2...........>1000000 etc!

Right now, I am trying to add libraryA to all of the sequences like

...

libraryA_1, >libraryA_2.........>libraryA_1000000. I can not figure out how to do it on Galaxy. Could somebody help to this end.

Thanks
