22 | // Manager object for merging/digitization | |
23 | // | |
24 | // Instance of this class manages the digitization and/or merging of | |
25 | // Sdigits into Digits. | |
26 | // | |
27 | // Only one instance of this class is created in the macro: | |
28 | // AliRunDigitizer * manager = | |
29 | // new AliRunDigitizer(nInputStreams,SPERB); | |
30 | // where nInputStreams is number of input streams and SPERB is | |
31 | // signals per background variable, which determines how combinations | |
32 | // of signal and background events are generated. | |
33 | // Then instances of specific detector digitizers are created: | |
34 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager) | |
35 | // and the I/O configured (you have to specify input files | |
36 | // and an output file). The manager connects appropriate trees from | |
37 | // the input files according a combination returned by AliMergeCombi | |
38 | // class. It creates TreeD in the output and runs once per | |
39 | // event Digitize method of all existing AliDetDigitizers | |
40 | // (without any option). AliDetDigitizers ask manager | |
41 | // for a TTree with input (manager->GetInputTreeS(Int_t i), | |
42 | // merge all inputs, digitize it, and save it in the TreeD | |
43 | // obtained by manager->GetTreeD(). Output events are stored with | |
44 | // numbers from 0, this default can be changed by | |
45 | // manager->SetFirstOutputEventNr(Int_t) method. The particle numbers | |
46 | // in the output are shifted by MASK, which is taken from manager. | |
47 | // | |
48 | // The default output is to the signal file (stream 0). This can be | |
49 | // changed with the SetOutputFile(TString fn) method. | |
50 | // | |
51 | // Single input file is permitted. Maximum kMaxStreamsToMerge can be merged. | |
52 | // Input from the memory (on-the-fly merging) is not yet | |
53 | // supported, as well as access to the input data by invoking methods | |
54 | // on the output data. | |
55 | // | |
56 | // Access to the some data is via gAlice for now (supposing the | |
57 | // same geometry in all input files), gAlice is taken from the first | |
58 | // input file on the first stream. | |
59 | // | |
60 | // Example with MUON digitizer, no merging, just digitization | |
61 | // | |
62 | // AliRunDigitizer * manager = new AliRunDigitizer(1,1); | |
63 | // manager->SetInputStream(0,"galice.root"); | |
64 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager); | |
65 | // manager->Exec(""); | |
66 | // | |
67 | // Example with MUON digitizer, merge all events from | |
68 | // galice.root (signal) file with events from bgr.root | |
69 | // (background) file. Number of merged events is | |
70 | // min(number of events in galice.root, number of events in bgr.root) | |
71 | // | |
72 | // AliRunDigitizer * manager = new AliRunDigitizer(2,1); | |
73 | // manager->SetInputStream(0,"galice.root"); | |
74 | // manager->SetInputStream(1,"bgr.root"); | |
75 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager); | |
76 | // manager->Exec(""); | |
77 | // | |
78 | // Example with MUON digitizer, save digits in a new file digits.root, | |
79 | // process only 1 event | |
80 | // | |
81 | // AliRunDigitizer * manager = new AliRunDigitizer(2,1); | |
82 | // manager->SetInputStream(0,"galice.root"); | |
83 | // manager->SetInputStream(1,"bgr.root"); | |
84 | // manager->SetOutputFile("digits.root"); | |
85 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager); | |
