  Dear ROOTers,

which is the proper way to specify the svcClass of a CASTOR file when using a TChain::Add?

While I am able to set svcClass=lhcbuser when using TFile::Open

root [0] TFile *_file0 =
TFile::Open("root://castorlhcb.cern.ch//castor/cern.ch/grid/lhcb/user/s/simone/2010_11/12435/12435999/DVNtuples.root?svcClass=lhcbuser") root [1] _file0->ls()
TXNetFile**
root://castorlhcb.cern.ch//castor/cern.ch/grid/lhcb/user/s/simone/2010_11/12435/12435999/DVNtuples.root Gaudi Trees
  TXNetFile*
root://castorlhcb.cern.ch//castor/cern.ch/grid/lhcb/user/s/simone/2010_11/12435/12435999/DVNtuples.root Gaudi Trees

   KEY: TDirectoryFile   DecayTreeTuple;1        DecayTreeTuple
   KEY: TDirectoryFile   GetIntegratedLuminosity;1       

GetIntegratedLuminosity

I cannot do the following:

root [0] TChain *fChain = new TChain("DecayTreeTuple/DecayTree") root [1]
fChain->Add("root://castorlhcb.cern.ch//castor/cern.ch/grid/lhcb/user/s/simone/2010_11/12435/12435999/DVNtuples.root?svcClass=lhcbuser") (Int_t)0
root [2] fChain->Scan()
(Long64_t)0

Thanks,
s.
