Hi, If you look in the documentation[1] 'source' is required. 'source' here means if the 'lib_dataset_id' provided is from a history or a data library. There used to be at least three options if I remember correctly, 'hda', 'hdda' and 'ldda'. From the error message Galaxy is returning it seems like now you need to choose between 'library' or 'hda'. Assuming you are importing a dataset from a library, try this: gi.histories.upload_dataset_from_library(historyID, datasetID, 'library') Or if that doesn't work: gi.histories.upload_dataset_from_library(historyID, datasetID, 'ldda') [1]http://bioblend.readthedocs.org/en/latest/api_docs/galaxy/all.html#bioblend.... Hope it helps, Carlos On Tue, Feb 11, 2014 at 8:33 AM, Pandori n <pandorinpan@gmail.com> wrote:

Hi,

Using Bioblend API to communicate with Galaxy

Try to import datasets to history, using command:

gi.histories.upload_dataset_from_library(historyID, datasetID)

But I've got the error:

bioblend.galaxy.client.ConnectionError: Unexpected response from galaxy: 400: "Please define the source ('library' or 'hda') and the content."

What's the source and the content? How to get it and put as arguments into this function?
