Hi Raja,
Thanks - at QMUL the two surls are the same (apart from a //) so it worked whereas at Glasgow they are different so it didn't. It was confusing that it worked at QMUL but not at Glasgow. I want to do this in a running job to get a particular replica to measure the bandwidth which is why I'm not using the Dirac tools.
Cheers
