Function documentation

AliTPCParam * GetTPCParam()

 create TPC param

void MakeAliases(TTree* tree)

 aliases definition

AliRecInfoMaker(const char* fnGenTracks, const char* fnCmpRes = "cmpTracks.root", const char* fnGalice = "galice.root", Int_t nEvents = 1, Int_t firstEvent = 0)








 AliRecInfoMaker - connencts the MC information with reconstructed information
 fnGenTracks  - file with MC to be created before using AliGenInfoMaker
 fnCmp        - file name  to be created
 fnGalice     - file with Loaders - usualy galice.root

 nEvent       - number of event s to be analyzed
 AliRecInfoMaker *t2 = new AliRecInfoMaker("genTracks.root","cmpESDTracks.root","galice.root",0,0);
