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 | // // | |
596a855f | 41 | // The name of the galice file can be changed from the default // |
e583c30d | 42 | // "galice.root" by passing it as argument to the AliReconstruction // |
43 | // constructor or by // | |
596a855f | 44 | // // |
45 | // rec.SetGAliceFile("..."); // | |
46 | // // | |
59697224 | 47 | // The local reconstruction can be switched on or off for individual // |
48 | // detectors by // | |
596a855f | 49 | // // |
59697224 | 50 | // rec.SetRunLocalReconstruction("..."); // |
596a855f | 51 | // // |
52 | // The argument is a (case sensitive) string with the names of the // | |
53 | // detectors separated by a space. The special string "ALL" selects all // | |
54 | // available detectors. This is the default. // | |
55 | // // | |
c71de921 | 56 | // The reconstruction of the primary vertex position can be switched off by // |
57 | // // | |
58 | // rec.SetRunVertexFinder(kFALSE); // | |
59 | // // | |
596a855f | 60 | // The tracking in ITS, TPC and TRD and the creation of ESD tracks can be // |
61 | // switched off by // | |
62 | // // | |
63 | // rec.SetRunTracking(kFALSE); // | |
64 | // // | |
65 | // The filling of additional ESD information can be steered by // | |
66 | // // | |
67 | // rec.SetFillESD("..."); // | |
68 | // // | |
69 | // Again, the string specifies the list of detectors. The default is "ALL". // | |
70 | // // | |
c71de921 | 71 | // The reconstruction requires digits or raw data as input. For the creation // |
72 | // of digits and raw data have a look at the class AliSimulation. // | |
596a855f | 73 | // // |
24f7a148 | 74 | // For debug purposes the method SetCheckPointLevel can be used. If the // |
75 | // argument is greater than 0, files with ESD events will be written after // | |
76 | // selected steps of the reconstruction for each event: // | |
77 | // level 1: after tracking and after filling of ESD (final) // | |
78 | // level 2: in addition after each tracking step // | |
79 | // level 3: in addition after the filling of ESD for each detector // | |
80 | // If a final check point file exists for an event, this event will be // | |
81 | // skipped in the reconstruction. The tracking and the filling of ESD for // | |
82 | // a detector will be skipped as well, if the corresponding check point // | |
83 | // file exists. The ESD event will then be loaded from the file instead. // | |
