Hi everyone, Does anybody know how Galaxy currently determines which outputs from a tool are shown when a workflow is run? I'm currently dynamically creating workflows based on the number of given inputs and iterating through all "HideDatasetAction*" for each tools "post_job_actions" to figure out the total number of steps that will be run.

"post_job_actions": { "HideDatasetActionoutput": { "action_arguments": {}, "action_type": "HideDatasetAction", "output_name": "output" }, "HideDatasetActionoutput_suppressed_reads_l": { "action_arguments": {}, "action_type": "HideDatasetAction", "output_name": "output_suppressed_reads_l" }, "HideDatasetActionoutput_suppressed_reads_r": { "action_arguments": {}, "action_type": "HideDatasetAction", "output_name": "output_suppressed_reads_r" }, "HideDatasetActionoutput_unmapped_reads_l": { "action_arguments": {}, "action_type": "HideDatasetAction", "output_name": "output_unmapped_reads_l" }, "HideDatasetActionoutput_unmapped_reads_r": { "action_arguments": {}, "action_type": "HideDatasetAction", "output_name": "output_unmapped_reads_r" } },

In the latest galaxy, there no longer seems to be any "HideDatasetAction*" in each tools "post_job_actions" options. How does Galaxy know which output files for a tool it should show or process?

Does it have to do something with "RenameDatasetAction*"?

"post_job_actions": { "RenameDatasetActionoutput_file": { "action_arguments": { "newname": "19_output_file" }, "action_type": "RenameDatasetAction", "output_name": "output_file" } },

Any guidance would be much appreciated. Thanks,
