Dear all, i try to run the following:

i have from my MC simulation the following outfiles

TString inFile="sim_tof_Bgfulljun08.root";
TString inFile2 = "sim_tof_Bgfulljun08____1.root";
TString inFile3 = "sim_tof_Bgfulljun08____2.root";

they are output of 10k event from urqmd generator.

to read them all, and be able to apply my digi task i do

fRun->SetInputFile(inFile.Data());

fRun->AddFile(inFile2.Data());
fRun->AddFile(inFile3.Data());

fRun->SetOutputFile(outFile);

the problem is now that i want
to use also another task for reco, and then i need

the digi output "outFile" and the MC output

TString inFile="sim_tof_Bgfulljun08.root";
TString inFile2 = "sim_tof_Bgfulljun08____1.root";
TString inFile3 = "sim_tof_Bgfulljun08____2.root";

so by using another macro to run my reco i do,

fRun->SetInputFile(inFile.Data());

fRun->AddFile(inFile2.Data());
fRun->AddFile(inFile3.Data());

fRun->AddFriend(outFile.Data());
fRun->SetOutputFile(RecoFile);

the problem is then that by using AddFile and AddFriend together
the files are not properly added and i the task doesn't find
the Tclonesarray from the files.

but if i do only

fRun->SetInputFile(inFile.Data());

fRun->AddFriend(outFile.Data());
fRun->SetOutputFile(RecoFile);

than it work,
can any of you help me?

thanks a lot
Alicia.

I had a similar problem more than one year ago:

And I think the problem is still there. Or at least I did some tries one week ago, and I was not able to make it work.

Hi Alicia

If i understand it correct you have several MC files but only one DIGI file.

Can you try the following

fRun->SetInputFile(inFile.Data());
fRun->AddFriend(outFile.Data());

fRun->AddFile(inFile2.Data());
fRun->AddFriend(outFile.Data());

fRun->AddFile(inFile3.Data());
fRun->AddFriend(outFile.Data());

fRun->SetOutputFile(RecoFile);

Ciao

Florian

Dear Florian,
thank you very much for your advice
now it seems work properly, anyway i have found some document attached by Mojhammad
http://www.gsi.de/documents/DOC-2004-Nov-122-1.ppt

I have also tried to do the same by using a macro
by doing Tchain with several files and then add also friend to them.

And also works but one has to do the following

Tchain * mychain =new TChain("cbmsim");
mychain->Add("file.root")
mychain->Add("file_2.root")
mychain->Add("file_3.root")

Tchain * myfriend =new TChain("cbmsim");
myfriend->Add("filefriend.root")

mychain->AddFriend(myfriend)

best regrads
ALicia.
