a38a7850 | 44 | // |
45 | // The current cluster finder for HLT | |
46 | // (Based on STAR L3) | |
01f43166 | 47 | // |
48 | //Basically we have two versions for the cluster finder now. | |
49 | //The default version, reads the data pad by pad, and find the | |
50 | //clusters as it reads the data. The other version has now been | |
51 | //developed to cope with unsorted data. New methods for the unsorted | |
52 | //version can be found at the end of the default one i the source file. | |
53 | //Currently the new version is only build to manage zero-suppressed data. | |
54 | //More functionality will be added later. | |
55 | // | |
a38a7850 | 56 | // The cluster finder is initialized with the Init function, |
57 | // providing the slice and patch information to work on. | |
58 | // | |
59 | // The input is a provided by the AliHLTTPCDigitReader class, | |
60 | // using the init() funktion, and the next() funktion in order | |
61 | // to get the next bin. Either packed or unpacked data can be | |
62 | // processed, dependent if one uses AliHLTTPCDigitReaderPacked | |
63 | // class or AliHLTTPCDigitReaderUnpacked class in the | |
64 | // Clusterfinder Component. | |
65 | // The resulting space points will be in the | |
66 | // array given by the SetOutputArray function. | |
67 | // | |
68 | // There are several setters which control the behaviour: | |
69 | // | |
70 | // - SetXYError(Float_t): set fixed error in XY direction | |
71 | // - SetZError(Float_t): set fixed error in Z direction | |
72 | // (used if errors are not calculated) | |
73 | // - SetDeconv(Bool_t): switch on/off deconvolution | |
74 | // - SetThreshold(UInt_t): set charge threshold for cluster | |
75 | // - SetMatchWidth(UInt_t): set the match distance in | |
76 | // time for sequences to be merged | |
77 | // - SetSTDOutput(Bool_t): switch on/off output about found clusters | |
78 | // - SetCalcErr(Bool_t): switch on/off calculation of | |
79 | // space point errors (or widths in raw system) | |
80 | // - SetRawSP(Bool_t): switch on/off convertion to raw system | |
81 | // | |
82 | // | |
83 | // Example Usage: | |
84 | // | |
85 | // AliHLTTPCFileHandler *file = new AliHLTTPCFileHandler(); | |
86 | // file->SetAliInput(digitfile); //give some input file | |
87 | // for(int slice=0; slice<=35; slice++){ | |
88 | // for(int patch=0; pat<6; pat++){ | |
89 | // file->Init(slice,patch); | |
90 | // UInt_t ndigits=0; | |
91 | // UInt_t maxclusters=100000; | |
92 | // UInt_t pointsize = maxclusters*sizeof(AliHLTTPCSpacePointData); | |
93 | // AliHLTTPCSpacePointData *points = (AliHLTTPCSpacePointData*)memory->Allocate(pointsize); | |
94 | // AliHLTTPCDigitRowData *digits = (AliHLTTPCDigitRowData*)file->AliAltroDigits2Memory(ndigits,event); | |
95 | // AliHLTTPCClusterFinder *cf = new AliHLTTPCClusterFinder(); | |
96 | // cf->SetMatchWidth(2); | |
97 | // cf->InitSlice( slice, patch, row[0], row[1], maxPoints ); | |
98 | // cf->SetSTDOutput(kTRUE); //Some output to standard IO | |
99 | // cf->SetRawSP(kFALSE); //Convert space points to local system | |
100 | // cf->SetThreshold(5); //Threshold of cluster charge | |
101 | // cf->SetDeconv(kTRUE); //Deconv in pad and time direction | |
102 | // cf->SetCalcErr(kTRUE); //Calculate the errors of the spacepoints | |
103 | // cf->SetOutputArray(points); //Move the spacepoints to the array | |
104 | // cf->Read(iter->fPtr, iter->fSize ); //give the data to the cf | |
105 | // cf->ProcessDigits(); //process the rows given by init | |
106 | // Int_t npoints = cf->GetNumberOfClusters(); | |
107 | // AliHLTTPCMemHandler *out= new AliHLTTPCMemHandler(); | |
108 | // out->SetBinaryOutput(fname); | |
109 | // out->Memory2Binary(npoints,points); //store the spacepoints | |
110 | // out->CloseBinaryOutput(); | |
111 | // delete out; | |
112 | // file->free(); | |
113 | // delete cf; | |
114 | // } | |
