[galaxy-dev] tasks (parralelism) and from_work_dir bug

Hi, I have tried to use tasks with tophat2, but I got the following bug.

multi.py +153 msg = 'nothing to merge for %s (expected %i files)' \ % (output_file_name, len(task_dirs))

This occurs because tophat2 tool uses from_work_dir feature to get the output files. But on the line: output_files = [ f for f in output_files if os.path.exists(f) ] It returnes an empty list because no real output files exists. Did anyone else have tried this before? Hagai
