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.
