Thanks for putting that in. I was wondering the same thing. The immediate use of it for me would be to have quality-checking steps at the beginning of the workflow, and to not proceed if the data does not pass. If there is any implementation of conditionals in Galaxy I would be interested! Thanks, Clare On Sun, May 22, 2011 at 2:00 PM, Florent Angly <florent.angly@gmail.com>wrote:

Hi all,
I was wondering if there is a way to put conditional statements in a Galaxy workflow.
This would be useful, for example, in the case of a workflow that has an optional advanced option that the user can click. This advanced option would add some extra steps to the data processing.
Another example of how this could be useful is if inside a workflow, the data needs to be processed differently based on the results of previous workflow steps. Say, you have a worflow that takes some sequences, and calculate their average length. Using a conditional statement, the workflow would put the data through DeBruijn assembler if the reads are small, but through a traditional Overlap-Layout-Consensus assembler if the reads are long.
Are conditional statements possible in Galaxy workflows and I just don't know how to use them?
Best,
Florent
