Dear all,

I have a question for MC file accessing.
Few simulation *.root files, which is produced as a simulation file, are splitted in pandaroot, automatically, because of a large amount of data size.

After running the simulation, I have total three files.
simulation.mc.root
simulation.mc_1.root
simulation.mc_2.root

How can I aceess all three files in digitization and reconstruction stage?

Thank you!

Hello,

As far as I recall you should use
fRun->AddFriend(file);
with every file subsequently. I think there was a even message about that in the forums earlier, but I cannot find it.

Kind regards, Ralf.

Thank you for you idea.

I think that addfriend() is slightly different concept, because it would have an extra information.

I assume that I need some kind of TChain class with the function of tchain->add();

I will try it, which you mentioned.

Thank you!

If I remember well it should be:

fRun->AddFile(namefile)
