Hi Robert, Thanks for you kind replay and I'm sorry for my semantic mistakes. Indeed, that's what I'm doing: qsub-ing different cshell scripts. Certainly, that's not the best approach and the only problem. I've unsuccessfully tried to set an os.environ and call qsub from it. However, subprocess.Popen seems not accept to run "qsub" over a second program. Do you have a over come to this issue? Code goes here: http://ompldr.org/vZDB5YQ
