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// //
973388c2 50// In case of raw-data reconstruction the user can modify the default //
51// number of events per digits/clusters/tracks file. In case the option //
52// is not used the number is set 1. In case the user provides 0, than //
53// the number of events is equal to the number of events inside the //
54// raw-data file (i.e. one digits/clusters/tracks file): //
55// //
56// rec.SetNumberOfEventsPerFile(...); //
57// //
58// //
596a855f 59// The name of the galice file can be changed from the default //
e583c30d 60// "galice.root" by passing it as argument to the AliReconstruction //
61// constructor or by //
596a855f 62// //
63// rec.SetGAliceFile("..."); //
64// //
59697224 65// The local reconstruction can be switched on or off for individual //
66// detectors by //
596a855f 67// //
59697224 68// rec.SetRunLocalReconstruction("..."); //
596a855f 69// //
70// The argument is a (case sensitive) string with the names of the //
71// detectors separated by a space. The special string "ALL" selects all //
72// available detectors. This is the default. //
73// //
c71de921 74// The reconstruction of the primary vertex position can be switched off by //
75// //
76// rec.SetRunVertexFinder(kFALSE); //
77// //
b8cd5251 78// The tracking and the creation of ESD tracks can be switched on for //
79// selected detectors by //
596a855f 80// //
b8cd5251 81// rec.SetRunTracking("..."); //
596a855f 82// //
c84a5e9e 83// Uniform/nonuniform field tracking switches (default: uniform field) //
84// //
1d99986f 85// rec.SetUniformFieldTracking(); ( rec.SetUniformFieldTracking(kFALSE); ) //
c84a5e9e 86// //
596a855f 87// The filling of additional ESD information can be steered by //
88// //
89// rec.SetFillESD("..."); //
90// //
b8cd5251 91// Again, for both methods the string specifies the list of detectors. //
92// The default is "ALL". //
93// //
94// The call of the shortcut method //
95// //
96// rec.SetRunReconstruction("..."); //
97// //
98// is equivalent to calling SetRunLocalReconstruction, SetRunTracking and //
99// SetFillESD with the same detector selecting string as argument. //
596a855f 100// //
c71de921 101// The reconstruction requires digits or raw data as input. For the creation //
102// of digits and raw data have a look at the class AliSimulation. //
596a855f 103// //
24f7a148 104// For debug purposes the method SetCheckPointLevel can be used. If the //
105// argument is greater than 0, files with ESD events will be written after //
106// selected steps of the reconstruction for each event: //
107// level 1: after tracking and after filling of ESD (final) //
108// level 2: in addition after each tracking step //
109// level 3: in addition after the filling of ESD for each detector //
110// If a final check point file exists for an event, this event will be //
111// skipped in the reconstruction. The tracking and the filling of ESD for //
112// a detector will be skipped as well, if the corresponding check point //
113// file exists. The ESD event will then be loaded from the file instead. //
