Salve,
I have a chain with many friend-chains and I would like save a subset of events in new trees. To do this, I use CloneTree tool.
This is the code:
Int_t i=0;
tree_clone[i++] = fChain->GetTree()->CloneTree(0);
TList *li = fChain->GetListOfFriends();
TIter next(li);
TFriendElement* T_friend=0;
while( (T_friend = (TFriendElement*)next()) ){
tree_clone[i++] = T_friend->GetTree()->CloneTree(0);
}
After creating the code, I apply some selection cuts and, for the selected events, I call the Fill() method for each one of the clone trees:
for(Int_t i=0; i <ntreemax>Fill();As a whole it seems to work (I get the cloned trees, with the number of entries I expect. I checked also the values of some variables and they look ok).
However, for some of the trees (not all) in the chains I get the following error message, when colling the Fill() method:
[quote]Error in : The element NDLevel2::unpackError type 103 (Int_t) is not supported yet
[/quote]
What is the meaning of this message?
Thank you in advance for the help,
Elena.
