f21fc003 | 20 | // AliDigitizationInput.cxx |
21 | // RS: Created from former AliDigitizationInput. It does not anymore manage digitization: | |
22 | // (now it is steared by the AliSimulation) but just provides input info for | |
23 | // AliDetector::SDigits2Ditits. | |
9ce40367 | 24 | // |
25 | // Manager object for merging/digitization | |
26 | // | |
27 | // Instance of this class manages the digitization and/or merging of | |
28 | // Sdigits into Digits. | |
29 | // | |
30 | // Only one instance of this class is created in the macro: | |
f21fc003 | 31 | // AliDigitizationInput * manager = |
32 | // new AliDigitizationInput(nInputStreams,SPERB); | |
a90ecf3c | 33 | // where nInputStreams is number of input streams and SPERB is |
34 | // signals per background variable, which determines how combinations | |
35 | // of signal and background events are generated. | |
9ce40367 | 36 | // Then instances of specific detector digitizers are created: |
37 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager) | |
a90ecf3c | 38 | // and the I/O configured (you have to specify input files |
39 | // and an output file). The manager connects appropriate trees from | |
40 | // the input files according a combination returned by AliMergeCombi | |
9ae76683 | 41 | // class. It creates TreeD in the output and runs once per |
a90ecf3c | 42 | // event Digitize method of all existing AliDetDigitizers |
43 | // (without any option). AliDetDigitizers ask manager | |
44 | // for a TTree with input (manager->GetInputTreeS(Int_t i), | |
9ce40367 | 45 | // merge all inputs, digitize it, and save it in the TreeD |
46 | // obtained by manager->GetTreeD(). Output events are stored with | |
47 | // numbers from 0, this default can be changed by | |
48 | // manager->SetFirstOutputEventNr(Int_t) method. The particle numbers | |
49 | // in the output are shifted by MASK, which is taken from manager. | |
50 | // | |
8d5e6345 | 51 | // The default output is to the signal file (stream 0). This can be |
52 | // changed with the SetOutputFile(TString fn) method. | |
53 | // | |
af7ba10c | 54 | // Single input file is permitted. Maximum MAXSTREAMSTOMERGE can be merged. |
9ce40367 | 55 | // Input from the memory (on-the-fly merging) is not yet |
56 | // supported, as well as access to the input data by invoking methods | |
57 | // on the output data. | |
58 | // | |
a90ecf3c | 59 | // Access to the some data is via gAlice for now (supposing the |
60 | // same geometry in all input files), gAlice is taken from the first | |
61 | // input file on the first stream. | |
9ce40367 | 62 | // |
314558d7 | 63 | // Example with MUON digitizer, no merging, just digitization |
64 | // | |
f21fc003 | 65 | // AliDigitizationInput * manager = new AliDigitizationInput(1,1); |
314558d7 | 66 | // manager->SetInputStream(0,"galice.root"); |
67 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager); | |
68 | // manager->Exec(""); | |
69 | // | |
70 | // Example with MUON digitizer, merge all events from | |
71 | // galice.root (signal) file with events from bgr.root | |
72 | // (background) file. Number of merged events is | |
73 | // min(number of events in galice.root, number of events in bgr.root) | |
74 | // | |
f21fc003 | 75 | // AliDigitizationInput * manager = new AliDigitizationInput(2,1); |

78 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager); | |
79 | // manager->Exec(""); | |
