20 | // class for running the reconstruction // |
21 | // // |
22 | // Clusters and tracks are created for all detectors and all events by // |
23 | // typing: // |
24 | // // |
25 | // AliReconstruction rec; // |
26 | // rec.Run(); // |
27 | // // |
28 | // The Run method returns kTRUE in case of successful execution. // |
c71de921 |
29 | // // |
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 // |
32 | // // |
33 | // rec.SetInput("..."); // |
34 | // // |
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 // |
40 | // // |
b26c3770 |
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 // |
44 | // // |
45 | // rec.SetEventRange(..., ...); // |
46 | // // |
47 | // The index -1 (default) can be used for the last event to indicate no // |
48 | // upper limit of the event range. // |
49 | // // |
596a855f |
50 | // The name of the galice file can be changed from the default // |
e583c30d |
51 | // "galice.root" by passing it as argument to the AliReconstruction // |
52 | // constructor or by // |
596a855f |
53 | // // |
54 | // rec.SetGAliceFile("..."); // |
55 | // // |
59697224 |
56 | // The local reconstruction can be switched on or off for individual // |
57 | // detectors by // |
596a855f |
58 | // // |
59697224 |
59 | // rec.SetRunLocalReconstruction("..."); // |
596a855f |
60 | // // |
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. // |
64 | // // |
c71de921 |
65 | // The reconstruction of the primary vertex position can be switched off by // |
66 | // // |
67 | // rec.SetRunVertexFinder(kFALSE); // |
68 | // // |
b8cd5251 |
69 | // The tracking and the creation of ESD tracks can be switched on for // |
70 | // selected detectors by // |
596a855f |
71 | // // |
b8cd5251 |
72 | // rec.SetRunTracking("..."); // |
596a855f |
73 | // // |
c84a5e9e |
74 | // Uniform/nonuniform field tracking switches (default: uniform field) // |
75 | // // |
76 | // rec.SetUniformFieldTracking(); ( rec.SetNonuniformFieldTracking(); ) // |
77 | // // |
596a855f |
78 | // The filling of additional ESD information can be steered by // |
79 | // // |
80 | // rec.SetFillESD("..."); // |
81 | // // |
b8cd5251 |
82 | // Again, for both methods the string specifies the list of detectors. // |
83 | // The default is "ALL". // |
84 | // // |
85 | // The call of the shortcut method // |
86 | // // |
87 | // rec.SetRunReconstruction("..."); // |
88 | // // |
89 | // is equivalent to calling SetRunLocalReconstruction, SetRunTracking and // |
90 | // SetFillESD with the same detector selecting string as argument. // |
596a855f |
91 | // // |
c71de921 |
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. // |
596a855f |
94 | // // |
24f7a148 |
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. // |
105 | // // |
