Hi, You're not alone with this request! Unfortunately I wasn't able to join the 2-day Galaxy Hackathon, but I heard from a colleague who just came back that this was one of the topics they worked on. At the end of the hackathon they had a working prototype: https://wiki.nbic.nl/index.php/NBIC_Galaxy_Hackathon_project#Loop_over_files... Since they had only 2 days, it will need some polish, but I heard this hack already made it into the development branch of Galaxy, so we may see something like this in the near future :) Cheers, Pi On Apr 15, 2011, at 4:28 PM, Dave Walton wrote:
I've essentially asked the same question of the list in the past and gotten no real response.
I have the same interest, but from a workflow perspective.
* A module that allows me to select multiple datafiles (say fastq files) * Then pass each data file to a separate instance of a workflow that runs tophat and cufflinks * then another module that takes the final outputs of each of the workflow runs and sends them to a final module that merges results.
I am attempting to implement something like this using the API, though the API is still pretty green from my perspective.
I think functionality like this built into the workflow editor would be a great addition.

Hi everyone,
I was wondering what would be the way in Galaxy to program the following:
- User clicks on a tool and form is displayed - They use a select multi menu in the form to pick lets say X multiple datasets from their history - When they click submit the tool launches X number of jobs in the history, on for each of the datasets selected.
I have a common use case where users have to manually run the same tool over and over again with the same parameters for each dataset of interest in their history. I would be great to be able programmatically or otherwise with Galaxy to be able to use one form and multi select the datasets and then launch the parallel jobs in one go.
regards, Leandro
