ROOT access to dcache files

Note that the TFile constructor cannot manage to open files on dcache (though it can open ROOT files on other filesystems) so you need to use the
TFile.Open method.
  • C++:

TFile::Open("dcache:/pnfs/aglt2.org/..."); //access without file handle

OR
TFile f;
f.Open("dcache:/pnfs/aglt2.org/... ");

OR
TFile *f = TFile::Open("dcache:/pnfs/aglt2.org/...");

  • pyRoot:
f = TFile.Open('dcache:/pnfs/aglt2.org/...')
