19// //
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. //
68// //
