39 | // Manager object for merging/digitization | |
40 | // | |
41 | // Instance of this class manages the digitization and/or merging of | |
42 | // Sdigits into Digits. | |
43 | // | |
44 | // Only one instance of this class is created in the macro: | |
a90ecf3c | 45 | // AliRunDigitizer * manager = |
46 | // new AliRunDigitizer(nInputStreams,SPERB); | |
47 | // where nInputStreams is number of input streams and SPERB is | |
48 | // signals per background variable, which determines how combinations | |
49 | // of signal and background events are generated. | |
9ce40367 | 50 | // Then instances of specific detector digitizers are created: |
51 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager) | |
a90ecf3c | 52 | // and the I/O configured (you have to specify input files |
53 | // and an output file). The manager connects appropriate trees from | |
54 | // the input files according a combination returned by AliMergeCombi | |
55 | // classcreates. It creates TreeD in the output and runs once per | |
56 | // event Digitize method of all existing AliDetDigitizers | |
57 | // (without any option). AliDetDigitizers ask manager | |
58 | // for a TTree with input (manager->GetInputTreeS(Int_t i), | |
9ce40367 | 59 | // merge all inputs, digitize it, and save it in the TreeD |
60 | // obtained by manager->GetTreeD(). Output events are stored with | |
61 | // numbers from 0, this default can be changed by | |
62 | // manager->SetFirstOutputEventNr(Int_t) method. The particle numbers | |
63 | // in the output are shifted by MASK, which is taken from manager. | |
64 | // | |
a90ecf3c | 65 | // Single input file is permitted. Maximum MAXSTREAMSTOMERGE can be merged. |
9ce40367 | 66 | // Input from the memory (on-the-fly merging) is not yet |
67 | // supported, as well as access to the input data by invoking methods | |
68 | // on the output data. | |
69 | // | |
a90ecf3c | 70 | // Access to the some data is via gAlice for now (supposing the |
71 | // same geometry in all input files), gAlice is taken from the first | |
72 | // input file on the first stream. | |
9ce40367 | 73 | // |
74 | // Example with MUON digitizer: | |
75 | // | |
a90ecf3c | 76 | // AliRunDigitizer * manager = new AliRunDigitizer(2,1); |
77 | // manager->SetInputStream(0,"1track_10events_phi45_60.root"); | |
78 | // manager->SetInputStream(1,"1track_10events_phi120_135.root"); | |
79 | // manager->SetOutputDir("/tmp"); | |
80 | // manager->SetOutputFile("digits.root"); | |
81 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager); | |
82 | // manager->SetNrOfEventsToWrite(1); | |
83 | // manager->Digitize(); | |
