Hi, I had no problems with providing my galaxy installation with datasets that were links to files in my filesystem, when I was using the SQLite database. But when I switched to a Postgres database, the links result in empty files when I choose links in the dataset upload. When I use actual "Load into galaxy" there is no problem, so it seems I just can't pass links to the Postgres database. Am I missing something? Database runs on the same machine as galaxy...
