Hi all, I have a strange problem when I am trying to run workflow using Galaxy API. If the workflow contains Tophat for Illumina, then when I am trying to use the "submit" API script in order to execute this workflow on some input dataset, I am strangely getting this HTTP error: "Error. 500 Internal Server Error The server has either erred or is incapable of performing the requested operation." Although the server has returned an error message, when I checked the "saved histories" I could notice that the job was successfully submitted and it is running! When I removed TopHat from the workflow, no error was returned... The thing is that I need the "dictionary" that is returned by the "submit" script. Has anyone encountered this problem before and know how to solve it? Thanks in advance! Liram
