Hi rooters,
I have problem to save list of objects (TH2F histograms) on Ttree.
I am running ROOT Version 3.02/07
After

TFile f_out(out_file,"recreate");
TTree *tree = new TTree("tree","2D matrix");

TList *list = new TList;

I create and fill number of TH2F histograms in the TList *list.

list->Add(hist);
hist -> Fill(x, y, 1);

Than I use special branch constructor TTree::Branch(TList*list, Int_t
bufsize, Int_t splitlevel)
as suggested on ROOTtalk.

tree->Branch(list,70000000,2);
tree->Fill();

But the output file seem to me does not contain any TH2F histograms.
Also I get messages "R__zip: source buffer too big".
Best regards,
/Pavel
