Hi, I am using a Taverna server to run a workflow based on Taverna tools service.
I can run execution correctly following the API here: http://dev.mygrid.org.uk/wiki/display/tav250/Conceptual+Interface The test workflow is very simple, taking a single input file. I noted that when I upload to the server the input file using: POST to https://myserver.ac.uk/taverna-server/rest/runs/42d06756-b9c4-45ef-b69d-a141c69499be//wd/IN and then associating the port to the file using: PUT to https://myserver.ac.uk/taverna-server/rest/runs/42d06756-b9c4-45ef-b69d-a141c69499be/input/input/input_file_text with data <t2sr:runInput xmlns:t2sr="http://ns.taverna.org.uk/2010/xml/server/rest/";> <t2sr:file>IN/myfile.txt</t2sr:file> </t2sr:runInput> execution is correct but input files are copied from the /tmp/42d06756-b9c4-45ef-b69d-a141c69499be to the Taverna Tool service working folder 'usecase....dir' I would like to avoid this copy because I would be dealing to substantial inputs and on a parameter sweep can affect performance. In Taverna Workbench this issue is solved in a elegant way using the "Set File Location" tab in the form input window. Files are not copied but replaced by symbolic links. *How can I achieve the same result via Taverna server API or a baclava (I noted the Set file location information is not saved inside the baclava)?* I tried to use the Taverna server API setting the input as reference as documented in: http://dev.mygrid.org.uk/wiki/display/tav250/Conceptual+Interface section: "Using a File Already on the Taverna Server Installation" Using: PUT https://myserver.ac.uk:8444/taverna-server/rest/runs/88f79b84-6451-4aed-b151-6b051328d922 /input/input/input_file_text with data ({'content-type': 'application/xml'}): <t2sr:runInput xmlns:t2sr="http://ns.taverna.org.uk/2010/xml/server/rest/";> <t2sr:reference> https://myserver.ac.uk:8444/taverna-server/rest/runs/88f79b84-6451-4aed-b151-6b051328d922/wd/IN/myfile.txt </t2sr:reference> </t2sr:runInput> I get the following 403 error: filename may not be absolute *Any Idea how to solve both issues?* Many thanks in advance.
