// Usage:
//   makeResults.C("tasks", "file_list", kGRID)
//   tasks : "ALL" or one/more of the following separated by space:
//     "EFF"  : TRD Tracking Efficiency 
//     "EFFC" : TRD Tracking Efficiency Combined (barrel + stand alone) - only in case of simulations
//     "RES"  : TRD tracking Resolution
//     "PID"  : TRD PID - pion efficiency 
//     "DET"  : Basic TRD Detector checks
//     "NOFR" : Data set does not have AliESDfriends.root 
//     "NOMC" : Data set does not have Monte Carlo Informations (real data), so all tasks which rely
//              on MC information are switched off
//   file_list : is the list of the files to be processed. 
//     They should contain the full path. Here is an example:
// /lustre/alice/local/TRDdata/SIM/P-Flat/TRUNK/RUN0/TRD.Performance.root
// or for GRID alien:///alice/cern.ch/user/m/mfasel/MinBiasProd/results/ppMinBias80000/1/TRD.Performance.root
//   kGRID : specify if files are comming from a GRID collection [default kFALSE]
//
// HOW TO BUILD THE FILE LIST
//   1. locally
// ls -1 BaseDir/RUN*/TRD.Performance.root > files.lst
// 
//   2. on Grid
// char *BaseDir="/alice/cern.ch/user/m/mfasel/MinBiasProd/results/ppMinBias80000/";
// TGrid::Connect("alien://");
// TGridResult *res = gGrid->Query(BaseDir, "%/TRD.Performance.root");
// TGridCollection *col = gGrid->OpenCollectionQuery(res);
// col->Reset();
// TMap *map = 0x0;
// while(map = (TMap*)col->Next()){
//   TIter it((TCollection*)map);
//   TObjString *info = 0x0;
//   while(info=(TObjString*)it()){
//     printf("alien://%s\n", col->GetLFN(info->GetString().Data()));
//   }
// }
//
// The files which will be processed are the intersection between the
// condition on the tasks and the files in the file list.
