Hi Rob,

Were you using a very old version of the library and examples or was it quite recent? In any case, try grabbing the script from https://github.com/afgane/bioblend/tree/master/docs/examples , we have done a lot of bugfixing and documentation recently. If you just want to test your setup there are also now some much simpler, less end-to-end example scripts that don't use any admin permissions, and we'll add a few more. 

The create_library step is the step where you're going to run into problems if you don't have admin rights to the Galaxy instance. If you're running on localhost though you should be able to set up the account as an admin account. 

Finally... we've put up some much better docs on using workflows (and libraries) in bioblend, which might be useful: http://bioblend.readthedocs.org/ and specifically http://bioblend.readthedocs.org/en/latest/api_docs/galaxy/docs.html#run-a-workflow

A lot of this is very recent so if you run into any bugs or anything that is just not clear, let me know, the feedback is very helpful!

Cheers,

Clare

I had trouble running blend4j, so I tried to jump into python (a language I have little experience with).

I tried running the example run_import_workflow.py 

% python run_imported_workflow.py http://localhost:8080 8c25bc83f6f9e4001dd21eb7b64f063f

but I get an error:

Is there anything I am missing from the stock configuration which would cause this not to run out of the box?

Cheers,

Rob
