Marcel, 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 https://bitbucket.org/galaxy/galaxy-central/src/76c18b38a3b8/scripts/api/README) for a some examples and hints to get you started. More detailed documentation should be available soon though. -Dannon On Jan 20, 2011, at 4:15 AM, Kempenaar, M (med) wrote: > Hello, > > Is it possible to let a tool in a workflow manage the users history?
