Brahms,
  I have a general root error that I don't understand.  I fill a ntuple with the variable eta_r2.  I save the ntuple in a root file using 
TFile *sf = new TFile("filename","RECREATE");
ntulpe->Write();
sf->Close();

When I try to draw eta_r2, I get this error message
Error in <TFile::ReadBuffer>: error reading all requested bytes from file FlowNT.root, got 0 of 28964
Error in <TBranch::GetBasket>: File: FlowNT.root at byte:0, branch:eta_r2, entry:-1
Error in <TFile::ReadBuffer>: error reading all requested bytes from file FlowNT.root, got 0 of 28964

  Does anyone know what could be wrong here?
Erik
