i'm resurrecting this thread to see if there's any more support for the idea
of deleting intermediate files in a workflow. i think this is an important
feature to have. oftentimes a workflow creates many intermediate files no
one will ever look at. and leaving it up to the user to cleanup their data
files is asking too much. there's another ticket regarding allow users to
still be able to preview the metadata of deleted workflow history items and
together these would go together nicely.

It isn't currently possible to delete datasets from within workflows. If
I'm understanding your situation correctly, to simplify the view of a
history after running a workflow, you could use the workflow output toggle
(the asterisk next to each output in the workflow editor view) and select
only the particular outputs you actually want to see. The rest of the
outputs are still in the destination history, but hidden from view by
default. This won't help you with disk space, though, so you might also
want to use the new functionality available for placing the results of a
workflow in a new history to accomplish what you want, deleting the previous
history that was cluttered with inputs after the workflow has run.
Regarding the Galaxy API, you can look at the README file in the
scripts/api/ directory of your galaxy installation (also at
for a some examples and hints to get you started. More detailed
documentation should be available soon though.

'replace' with the single merged file.
