"Loop over datasets in repository?"

Question

Dear All,

How to execute the same process for different datasets in your repository?
I can't figure out how to use the "Loop Repository" operator.

Best regards,

Wessel

Hi,
This process has no errors, although it is a bit weird that you retrieve each dataset twice:

Nope, it works like a charm. Don't get confused by the first two data sets: they differ only in the fact that one time there is a label and one time there is none. So there are indeed two copies of Golf in the sample repository.

By the way: Those are not "errors" but "potential problems" as stated at top of the "Problem" view. And indeed the meta data is underspecified so it cannot be guaranteed that the process will run without actually executing it  :P

Cheers,
Ingo

Dear Ingo,

Thanks a lot.
This works like a charm.

Unfortunately it gives both warnings and errors:
- Expected ExampleSet but received IOObject.
- Meta data is underspecified. Cannot check precondition.
I use this in a process and get these errors more than 20 times.
This is a bit of a bummer because now I can't see other actually important errors.

Best regards,

Wessel

edit: I think the trick is to pass the meta data from the first dataset in the folder.
