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. // | |
29 | // The name of the galice file can be changed from the default // | |
e583c30d | 30 | // "galice.root" by passing it as argument to the AliReconstruction // |
31 | // constructor or by // | |
596a855f | 32 | // // |
33 | // rec.SetGAliceFile("..."); // | |
34 | // // | |
59697224 | 35 | // The local reconstruction can be switched on or off for individual // |
36 | // detectors by // | |
596a855f | 37 | // // |
59697224 | 38 | // rec.SetRunLocalReconstruction("..."); // |
596a855f | 39 | // // |
40 | // The argument is a (case sensitive) string with the names of the // | |
41 | // detectors separated by a space. The special string "ALL" selects all // | |
42 | // available detectors. This is the default. // | |
43 | // // | |
44 | // The tracking in ITS, TPC and TRD and the creation of ESD tracks can be // | |
45 | // switched off by // | |
46 | // // | |
47 | // rec.SetRunTracking(kFALSE); // | |
48 | // // | |
49 | // The filling of additional ESD information can be steered by // | |
50 | // // | |
51 | // rec.SetFillESD("..."); // | |
52 | // // | |
53 | // Again, the string specifies the list of detectors. The default is "ALL". // | |
54 | // // | |
55 | // The reconstruction requires digits as input. For the creation of digits // | |
56 | // have a look at the class AliSimulation. // | |
57 | // // | |
24f7a148 | 58 | // For debug purposes the method SetCheckPointLevel can be used. If the // |
59 | // argument is greater than 0, files with ESD events will be written after // | |
60 | // selected steps of the reconstruction for each event: // | |
61 | // level 1: after tracking and after filling of ESD (final) // | |
62 | // level 2: in addition after each tracking step // | |
63 | // level 3: in addition after the filling of ESD for each detector // | |
64 | // If a final check point file exists for an event, this event will be // | |
65 | // skipped in the reconstruction. The tracking and the filling of ESD for // | |
66 | // a detector will be skipped as well, if the corresponding check point // | |
67 | // file exists. The ESD event will then be loaded from the file instead. // | |
