19// //
20// class for running generation, simulation and digitization //
21// //
22// Hits, sdigits and digits are created for all detectors by typing: //
23// //
24// AliSimulation sim; //
25// sim.Run(); //
26// //
27// The Run method returns kTRUE in case of successful execution. //
28// The number of events can be given as argument to the Run method or it //
29// can be set by //
30// //
31// sim.SetNumberOfEvents(n); //
32// //
95601147 33// The name of the configuration file can be passed as argument to the //
34// AliSimulation constructor or can be specified by //
85a5290f 35// //
36// sim.SetConfigFile("..."); //
37// //
38// The generation of particles and the simulation of detector hits can be //
39// switched on or off by //
40// //
41// sim.SetRunGeneration(kTRUE); // generation of primary particles //
42// sim.SetRunSimulation(kFALSE); // but no tracking //
43// //
44// For which detectors sdigits and digits will be created, can be steered //
45// by //
46// //
47// sim.SetMakeSDigits("ALL"); // make sdigits for all detectors //
48// sim.SetMakeDigits("ITS TPC"); // make digits only for ITS and TPC //
49// //
50// The argument is a (case sensitive) string with the names of the //
51// detectors separated by a space. An empty string ("") can be used to //
52// disable the creation of sdigits or digits. The special string "ALL" //
53// selects all available detectors. This is the default. //
54// //
55// The creation of digits from hits instead of from sdigits can be selected //
56// by //
57// //
58// sim.SetMakeDigitsFromHits("TRD"); //
59// //
60// The argument is again a string with the selected detectors. Be aware that //
61// this feature is not available for all detectors and that merging is not //
62// possible, when digits are created directly from hits. //
63// //
05526d44 64// Background events can be merged by calling //
85a5290f 65// //
66// sim.MergeWith("background/galice.root", 2); //
67// //
68// The first argument is the file name of the background galice file. The //
69// second argument is the number of signal events per background event. //
05526d44 70// By default this number is calculated from the number of available //
71// background events. MergeWith can be called several times to merge more //
72// than two event streams. It is assumed that the sdigits were already //
73// produced for the background events. //
85a5290f 74// //
0421c3d1 75// The output of raw data can be switched on by calling //
76// //
77// sim.SetWriteRawData("MUON"); // write raw data for MUON //
78// //
06c7e392 79// The default output format of the raw data are DDL files. They are //
80// converted to a DATE file, if a file name is given as second argument. //
81// For this conversion the program "dateStream" is required. If the file //
82// name has the extension ".root", the DATE file is converted to a root //
83// file. The program "alimdc" is used for this purpose. For the conversion //
84// to DATE and root format the two conversion programs have to be installed. //
85// Only the raw data in the final format is kept if the third argument is //
86// kTRUE. //
87// //
0421c3d1 88// The methods RunSimulation, RunSDigitization, RunDigitization, //
89// RunHitsDigitization and WriteRawData can be used to run only parts of //
06c7e392 90// the full simulation chain. The creation of raw data DDL files and their //
91// conversion to the DATE or root format can be run directly by calling //
92// the methods WriteRawFiles, ConvertRawFilesToDate and ConvertDateToRoot. //
95601147 93// //
18b43626 94// The default number of events per file, which is usually set in the //
95// config file, can be changed for individual detectors and data types //
96// by calling //
97// //
98// sim.SetEventsPerFile("PHOS", "Reconstructed Points", 3); //
99// //
100// The first argument is the detector, the second one the data type and the //
101// last one the number of events per file. Valid data types are "Hits", //
102// "Summable Digits", "Digits", "Reconstructed Points" and "Tracks". //
103// The number of events per file has to be set before the simulation of //
104// hits. Otherwise it has no effect. //
105// //
