Hello Clare,

This enhancement request is still in on our to-do list for the public/distribution Galaxy instances. Following the open bitbucket ticket is the best way to follow status.

Conditional workflow processes/tools have been discussed in several threads on the galaxy-dev@bx.psu.edu mailing list, if you are interested:

Best!

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

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
