[galaxy-dev] Folder permissions after cluster run

Hi, We are running galaxy on the cluster with the 'real user' submission. It all works fine, but at the end of the run we found something unexpected. All the .dat files in the file_path folder are owned by the user running Galaxy, but all the folders (e.g. dataset_25808_files) are still owned by the user that was running the tool on the cluster. Is this the expected outcome or is there something wrong? Thanks for your help, Sajoscha
