3 How to make a comparison using MC information:
6 0. Build the MC info tree
8 gSystem->Load("libPWG1.so")
9 AliGenInfoMaker *t = new AliGenInfoMaker("galice.root","genTracks.root",0,0)
13 1. Build the reconstructed info tree
16 gSystem->Load("libPWG1.so");
18 AliRecInfoMaker *t2 = new AliRecInfoMaker("genTracks.root","cmpESDTracks.root","galice.root",0,0);
23 2. Make a chain of the information tree
25 gSystem->Load("libPWG1.so");
29 .L /u/miranov/macroxrdproof64/AliXRDPROOFtoolkit.cxx+
30 AliXRDPROOFtoolkit tool;
31 TChain * chain = tool.MakeChain("pp.txt","ESDcmpTracks",0,1000)
33 .L $ALICE_ROOT/PWG1/AliComparisonSelector.cxx+
38 a.) Use AliTreeDraw for fast prototyping the queries - analysis type:
40 gSystem->Load("libPWG1.so");
47 chain->Process("$ALICE_ROOT/PWG1/AliComparisonSelector.cxx+")
50 TFile f("Output.root");
