Hi Thomas,
you should do:
TFile * file ...
...
file->cd();
object->Write("keyname")
Histograms are special, they belong to the directory of TFile file,
file->Write() writes all objects in that directory:
TFile *file = new TFile
TH1F * h = new TH1F(... // this adds h to the cwd (which is: file)
..
cheers
Otto
