Hi Stefano,

I think AddFriend is used when you want to merge infos from two different trees, but sort of "paralel": e.g. in tree1 you store energy loss and in tree2 you store momenta for the same collection of events.
If you want to add trees one after the other, you should rather use the chain mechanism, I guess:
TChain t("cbmsim");
t.AddFile("$DATA/panda/kick/bigdata_mega.root");
t.AddFile("$DATA/panda/kick/bigdata_mega_1.root");
etc...

hope that helps,
ola
