Closed:Issue assigning unique ID's to a CWL pipeline

Question

[Tony.D]

Hi everyone,

I have been playing around with CWL and am currently stumped with the unique identifier option. I have assigned an unique identifier to one of my input files in my pipeline, which runs successfully. However, how can I use this ID to track provenance? Is there some way that CWL permanently associates a file with an ID, so that at the end of a workflow, the user can identify which ID's were associated with a given file(s)? Or CWL only accepts a file as input with a specific ID?

I have confused with the use of unique ID's in CWL and would appreciate if someone could clarify this for me.

Thank you for the help.
