20 // class for running generation, simulation and digitization //
22 // Hits, sdigits and digits are created for all detectors by typing: //
24 // AliSimulation sim; //
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 //
31 // sim.SetNumberOfEvents(n); //
33 // The name of the configuration file can be passed as argument to the //
34 // AliSimulation constructor or can be specified by //
36 // sim.SetConfigFile("..."); //
38 // The generation of particles and the simulation of detector hits can be //
39 // switched on or off by //
41 // sim.SetRunGeneration(kTRUE); // generation of primary particles //
42 // sim.SetRunSimulation(kFALSE); // but no tracking //
44 // For which detectors sdigits and digits will be created, can be steered //
47 // sim.SetMakeSDigits("ALL"); // make sdigits for all detectors //
48 // sim.SetMakeDigits("ITS TPC"); // make digits only for ITS and TPC //
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. //
55 // The creation of digits from hits instead of from sdigits can be selected //
58 // sim.SetMakeDigitsFromHits("TRD"); //
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. //
64 // Background events can be merged by calling //
66 // sim.MergeWith("background/galice.root", 2); //
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. //
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. //
75 // The output of raw data can be switched on by calling //
77 // sim.SetWriteRawData("MUON"); // write raw data for MUON //
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 //
88 // The methods RunSimulation, RunSDigitization, RunDigitization, //
89 // RunHitsDigitization and WriteRawData can be used to run only parts of //
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. //
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 //
98 // sim.SetEventsPerFile("PHOS", "Reconstructed Points", 3); //
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. //
