Dear all,
I am trying to open a file on CASTOR, fill it with a root tree and close it. What I do is the following:
TFile *outfile;
TString outstring;
TTree *tree;
…
tree = new TTree(“tree”,“data tree”);
outfile = TFile::Open(outstring,“RECREATE”);//outstring.Data());//(outstring,“RECREATE”);
(stuff)
tree->Write();
outfile->Write();
outfile->Close();
where outstring is of the type "rfio:///cern.ch…"
The file is correctly opened in the location I want and filled with data, but when I try to open it with root no trace of the TTree key is there. For example a .ls() command (once the root file is opened) yields no “KEY: TTree tree;1 data tree”, which is what I got when I created the file “locally” (i.e. producing the output in my local directory and not on CASTOR, with some slightly different code).
What am I doing wrong?
Thanks for your help.
Cheers
