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. // | |
