Cheers,

Subject: [ROOT] Creating a tree in a file


Hi all,

I'm creating several files first and afterwards the correspoding trees. 
How is the correct syntax to create a tree in a file? (like 
TTree::Branch, there is not TFile::Tree)

Actually I'm doing:

TDirectory *save = gDirectory;
file->cd();
new TTree(...)
gDirectory=save;

Thanks,
Thomas.
