-//-----------------------------------------------------------------
-// Implementation of the TPC Kr cluster class
-//
-// Origin: Adam Matyja, INP PAN, adam.matyja@ifj.edu.pl
-//-----------------------------------------------------------------
-
-/*
-Instruction - how to use that:
-There are two macros prepared. One is for preparing clusters from MC
-samples: FindKrClusters.C. The output is kept in TPC.RecPoints.root.
-The other macro is prepared for data analysis: FindKrClustersRaw.C.
-The output is created for each processed file in root file named adc.root.
-For each data subsample the same named file is created. So be careful
-do not overwrite them.
-
-Additional selection criteria to select the GOLD cluster
-Example:
-// open file with clusters
-TFile f("Krypton.root");
-TTree * tree = (TTree*)f.Get("Kr")
-TCut cutR0("cutR0","fADCcluster/fSize<100"); // adjust it according v seetings -
-TCut cutR1("cutR1","fADCcluster/fSize>7"); // cosmic tracks and noise removal
-TCut cutR2("cutR2","fMax.fAdc/fADCcluster<0.2"); // digital noise removal
-TCut cutR3("cutR3","fMax.fAdc/fADCcluster>0.01"); // noise removal
-TCut cutS1("cutS1","fSize<200"); // adjust it according v seetings - cosmic tracks
-TCut cutAll = cutR0+cutR1+cutR2+cutR3+cutS1;
-This values are typical values to be applied in selectors
-
-
-*
-**** MC ****
-*
-
-To run clusterizaton for MC type:
-.x FindKrClusters.C
-
-If you don't want to use the standard selection criteria then you
-have to do following:
-
-// load the standard setup
-AliRunLoader* rl = AliRunLoader::Open("galice.root");
-AliTPCLoader *tpcl = (AliTPCLoader*)rl->GetLoader("TPCLoader");
-tpcl->LoadDigits();
-rl->LoadgAlice();
-gAlice=rl->GetAliRun();
-TDirectory *cwd = gDirectory;
-AliTPCv4 *tpc = (AliTPCv4*)gAlice->GetDetector("TPC");
-Int_t ver = tpc->IsVersion();
-rl->CdGAFile();
-AliTPCParam *param=(AliTPCParamSR *)gDirectory->Get("75x40_100x60_150x60");
-AliTPCDigitsArray *digarr=new AliTPCDigitsArray;
-digarr->Setup(param);
-cwd->cd();
-
-//loop over events
-Int_t nevmax=rl->GetNumberOfEvents();
-for(Int_t nev=0;nev<nevmax ;nev++){
- rl->GetEvent(nev);
- TTree* input_tree= tpcl->TreeD();//load tree with digits
- digarr->ConnectTree(input_tree);
- TTree *output_tree =tpcl->TreeR();//load output tree
-
- AliTPCclustererKr *clusters = new AliTPCclustererKr();
- clusters->SetParam(param);
- clusters->SetInput(input_tree);
- clusters->SetOutput(output_tree);
- clusters->SetDigArr(digarr);
-
-//If you want to change the cluster finder parameters for MC there are
-//several of them:
-
-//1. signal threshold (everything below the given number is treated as 0)
- clusters->SetMinAdc(3);
-
-//2. number of neighbouring timebins to be considered
- clusters->SetMinTimeBins(2);
-
-//3. distance of the cluster center to the center of a pad in pad-padrow plane
-//(in cm). Remenber that this is still quantified by pad size.
- clusters->SetMaxPadRangeCm(2.5);
-
-//4. distance of the cluster center to the center of a padrow in pad-padrow
-//plane (in cm). Remenber that this is still quantified by pad size.
- clusters->SetMaxRowRangeCm(3.5);
-
-//5. distance of the cluster center to the max time bin on a pad (in tackts)
-//ie. fabs(centerT - time)<7
- clusters->SetMaxTimeRange(7);
-
-//6. cut reduce peak at 0. There are noises which appear mostly as two
-//timebins on one pad.
- clusters->SetValueToSize(3.5);
-
-
- clusters->finderIO();
- tpcl->WriteRecPoints("OVERWRITE");

-delete rl;//cleans everything

-********* DATA *********
-*
-
-To run clusterizaton for DATA for file named raw_data.root type:
-.x FindKrClustersRaw.C("raw_data.root")
-

-
-//
-// remove Altro warnings

+// Origin: Adam Matyja, INP PAN, adam.matyja@ifj.edu.pl\r

+\r
+/*\r
+Instruction - how to use that:\r
+There are two macros prepared. One is for preparing clusters from MC \r
+samples: FindKrClusters.C. The output is kept in TPC.RecPoints.root.\r
+The other macro is prepared for data analysis: FindKrClustersRaw.C. \r
+The output is created for each processed file in root file named adc.root. \r
+For each data subsample the same named file is created. So be careful \r
+do not overwrite them. \r
+\r
+Additional selection criteria to select the GOLD cluster\r
+Example:\r
+// open file with clusters\r
+TFile f("Krypton.root");\r
+TTree * tree = (TTree*)f.Get("Kr")\r
+TCut cutR0("cutR0","fADCcluster/fSize<100"); // adjust it according v seetings - \r
+TCut cutR1("cutR1","fADCcluster/fSize>7"); // cosmic tracks and noise removal\r
+TCut cutR2("cutR2","fMax.fAdc/fADCcluster<0.2"); // digital noise removal\r
+TCut cutR3("cutR3","fMax.fAdc/fADCcluster>0.01"); // noise removal\r
+TCut cutS1("cutS1","fSize<200"); // adjust it according v seetings - cosmic tracks\r
+TCut cutAll = cutR0+cutR1+cutR2+cutR3+cutS1;\r
+This values are typical values to be applied in selectors\r
+\r

+**** MC ****\r

+//1. signal threshold (everything below the given number is treated as 0)\r
