20 // class for running the reconstruction //
22 // Clusters and tracks are created for all detectors and all events by //
25 // AliReconstruction rec; //
28 // The Run method returns kTRUE in case of successful execution. //
30 // If the input to the reconstruction are not simulated digits but raw data, //
31 // this can be specified by an argument of the Run method or by the method //
33 // rec.SetInput("..."); //
35 // The input formats and the corresponding argument are: //
36 // - DDL raw data files: directory name, ends with "/" //
37 // - raw data root file: root file name, extension ".root" //
38 // - raw data DATE file: DATE file name, any other non-empty string //
39 // - MC root files : empty string, default //
41 // By default all events are reconstructed. The reconstruction can be //
42 // limited to a range of events by giving the index of the first and the //
43 // last event as an argument to the Run method or by calling //
45 // rec.SetEventRange(..., ...); //
47 // The index -1 (default) can be used for the last event to indicate no //
48 // upper limit of the event range. //
50 // The name of the galice file can be changed from the default //
51 // "galice.root" by passing it as argument to the AliReconstruction //
52 // constructor or by //
54 // rec.SetGAliceFile("..."); //
56 // The local reconstruction can be switched on or off for individual //
59 // rec.SetRunLocalReconstruction("..."); //
61 // The argument is a (case sensitive) string with the names of the //
62 // detectors separated by a space. The special string "ALL" selects all //
63 // available detectors. This is the default. //
65 // The reconstruction of the primary vertex position can be switched off by //
67 // rec.SetRunVertexFinder(kFALSE); //
69 // The tracking and the creation of ESD tracks can be switched on for //
70 // selected detectors by //
72 // rec.SetRunTracking("..."); //
74 // Uniform/nonuniform field tracking switches (default: uniform field) //
76 // rec.SetUniformFieldTracking(); ( rec.SetNonuniformFieldTracking(); ) //
78 // The filling of additional ESD information can be steered by //
80 // rec.SetFillESD("..."); //
82 // Again, for both methods the string specifies the list of detectors. //
83 // The default is "ALL". //
85 // The call of the shortcut method //
87 // rec.SetRunReconstruction("..."); //
89 // is equivalent to calling SetRunLocalReconstruction, SetRunTracking and //
90 // SetFillESD with the same detector selecting string as argument. //
92 // The reconstruction requires digits or raw data as input. For the creation //
93 // of digits and raw data have a look at the class AliSimulation. //
95 // For debug purposes the method SetCheckPointLevel can be used. If the //
96 // argument is greater than 0, files with ESD events will be written after //
97 // selected steps of the reconstruction for each event: //
98 // level 1: after tracking and after filling of ESD (final) //
99 // level 2: in addition after each tracking step //
100 // level 3: in addition after the filling of ESD for each detector //
101 // If a final check point file exists for an event, this event will be //
102 // skipped in the reconstruction. The tracking and the filling of ESD for //
103 // a detector will be skipped as well, if the corresponding check point //
104 // file exists. The ESD event will then be loaded from the file instead. //
