Hi all, I was trying to add a data source tool in our instance which connects to an S3 bucket, where the dataset will is hosted. The tool (the data source page) appears on the main panel but when I try to retrieve a dataset from the source, it does not appear on the history panel but rather downloads outside of Galaxy. [image: Inline image 1] The tool xml looks like this: <tool name="S3 test" id="s3_test" tool_type="data_source" version="1.0.1"> <description>Datasource s3</description> <command interpreter="python"> data_source.py $output $__app__.config.output_size_limit </command> <inputs action=" http://mybucket.s3-website-ap-southeast-1.amazonaws.com/index_sendToGalaxy.h..." check_values="false" method="post" target="_top"> <display>go to Sync Datasource $GALAXY_URL</display> <param name="GALAXY_URL" type="baseurl" value="/tool_runner?tool_id=s3_test" /> </inputs> <request_param_translation> <request_param galaxy_name="URL" remote_name="URL" missing="" /> <request_param galaxy_name="URL_method" remote_name="URL_method" missing="get" /> </request_param_translation> <outputs> <data name="output" format="auto" /> </outputs> <options sanitize="False" refresh="True"/> </tool> Is there anything I still need to add in the tool xml? Any advice on how I could proceed with this? Thanks and Best Regards, Venice Juanillas
