Dear all,
it is not so clear to me why this procedure does not work in my case.
I have run the simulation, which produces two files: points_tpccombi.root and points_tpcombi_1.root.
Then digitization, one output file: digi_tpccombi.root.

At the end reconstruction, but I need also the MC information.
I have written:

FairRunAna *fRun= new FairRunAna();
fRun->SetInputFile("points_tpccombi.root");
fRun->AddFriend("digi_tpccombi.root");
fRun->AddFile("points_tpccombi_1.root");
fRun->AddFriend("digi_tpccombi.root");
fRun->SetOutputFile(outFile);


The first file is processed normally, but when the second file starts:


-I FairRootManager: switching to chained file: points_tpccombi_1.root
connected friends: digi_tpccombi.root


after few events I have a segmentation violation, related to the wrong coupling of the initial file and his friend.

Has somebody managed to handle different friend files in a reconstruction macro? And how? It seems Alicia's method is not working for me (no idea why)
Thanks in advance.
