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// //
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// //
74// The filling of additional ESD information can be steered by //
75// //
76// rec.SetFillESD("..."); //
77// //
b8cd5251 78// Again, for both methods the string specifies the list of detectors. //
79// The default is "ALL". //
80// //
81// The call of the shortcut method //
82// //
83// rec.SetRunReconstruction("..."); //
84// //
85// is equivalent to calling SetRunLocalReconstruction, SetRunTracking and //
86// SetFillESD with the same detector selecting string as argument. //
596a855f 87// //
c71de921 88// The reconstruction requires digits or raw data as input. For the creation //
89// of digits and raw data have a look at the class AliSimulation. //
596a855f 90// //
24f7a148 91// For debug purposes the method SetCheckPointLevel can be used. If the //
92// argument is greater than 0, files with ESD events will be written after //
93// selected steps of the reconstruction for each event: //
94// level 1: after tracking and after filling of ESD (final) //
95// level 2: in addition after each tracking step //
96// level 3: in addition after the filling of ESD for each detector //
97// If a final check point file exists for an event, this event will be //
98// skipped in the reconstruction. The tracking and the filling of ESD for //
99// a detector will be skipped as well, if the corresponding check point //
100// file exists. The ESD event will then be loaded from the file instead. //
