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. //
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. //
