Hi,
I try to work in a ntuple linked to another in CASTOR, but when I run 
ROOT, it tell me that:
Error in <TFile::TFile>: file ../ROOT-file/ntuple/pim5h_ela0.root does not exist
Error in <TROOT::cd>: Unknown directory CBNT
Error in <TFile::TFile>: file ntuple.root does not exist

I have put in the file.C:
TFile *f = new TFile("../ROOT-file/ntuple/pim5h_ela0.root");
TTree *t = (TTree *) gDirectory->Get("CBNT/t3333");
Analisis * aa = new Analisis(t);
aa->Histo();

I'm only managed to work with it, if I copy the ntuple to my directory 
from CASTOR with rfcp.

But these kind of ntuples are very large and I prefer work with it from 
CASTOR.
How I can do it?

Cheers,

Carmen.
