Hi Iouri,

My guess is that  
    The result is "Error in <TFile::cd> Unknown directory db".
Means that you have code looking like
	file->cd("db");
And that the directory 'db' does not exist in your file.

> I use the macro similar to copytree.C for production root ntuple from CDF
STNtuple.

Did you make sure that the directory hiearchy was properly 'copied' over to
your new file?

Cheers,
Philippe.

Hi, 

I use the macro similar to copytree.C for production root ntuple from CDF
STNtuple. The result is OK. But I can not make analysis of new ntuple. The
result is "Error in <TFile::cd> Unknown directory db".
What is a reason of this error?

with best regards, Yuri
