Just reran this tool and it did indeed give me multiple outputs. I think the problem is the files appear but the history needs to be refreshed to see them. There is a little refresh icon at the top of the history panel that is needed. This is a known limitation of the multiple file output support currently. If the tool outputs pretty regular homogeneous files, it is probably worth investigating outputting a collection of files instead of individual files. This way these files can be used in workflows for instance and operated on as a group. -John On Thu, Sep 3, 2015 at 4:02 PM, srodriguez <srodriguez@toulouse.inra.fr> wrote:

Hi,

I am developing a tool with unknown output dataset number; so, I am trying to use discover_datasets tag.

I have tested the following code as explained in the galaxy project documentation:

https://bitbucket.org/galaxy/galaxy-central/raw/d1f51ff3c495b52b621ea6562ef5...

But, when I look at he result, I only obtain a single dataset corresponding to the "report".

When I check in the job_working_directory, no "subdir(1,2 and 3)" folders have been created and no datasets displayed on galaxy as results.

Can someone help me understand how discover_datasets work and why all the supposed multi datasets are not displayed in the galaxy interface?

Thanks in advance.

Best regards,
