a08ddb28 | 18 | Revision 1.15 2002/04/09 13:38:47 jchudoba |
19 | Add const to the filename argument | |
20 | ||
3466e07f | 21 | Revision 1.14 2002/04/04 09:28:04 jchudoba |
22 | Change default names of TPC trees. Use update instead of recreate for the output file. Overwrite the AliRunDigitizer object in the output if it exists. | |
23 | ||
9b31ff31 | 24 | Revision 1.13 2002/02/13 09:03:32 jchudoba |
25 | Pass option to subtasks. Delete input TTrees. Use gAlice from memory if it is present (user must delete the default one created by aliroot if he/she wants to use gAlice from the input file!). Add new data member to store name of the special TPC TTrees. | |
26 | ||
f042097d | 27 | Revision 1.12 2001/12/10 16:40:52 jchudoba |
28 | Import gAlice from the signal file before InitGlobal() to allow detectors to use it during initialization | |
29 | ||
7e68127f | 30 | Revision 1.11 2001/12/03 07:10:13 jchudoba |
31 | Default ctor cannot create new objects, create dummy default ctor which leaves object in not well defined state - to be used only by root for I/O | |
32 | ||
314558d7 | 33 | Revision 1.10 2001/11/15 11:07:25 jchudoba |
34 | Set to zero new pointers to TPC and TRD special trees in the default ctor. Add const to all Get functions. Remove unused constant, rename constant according coding rules. | |
35 | ||
9ae76683 | 36 | Revision 1.9 2001/11/15 09:00:11 jchudoba |
37 | Add special treatment for TPC and TRD, they use different trees than other detectors | |
38 | ||
f34e67f9 | 39 | Revision 1.8 2001/10/21 18:38:43 hristov |
40 | Several pointers were set to zero in the default constructors to avoid memory management problems | |
41 | ||

63 | // Manager object for merging/digitization | |
64 | // | |
65 | // Instance of this class manages the digitization and/or merging of | |
66 | // Sdigits into Digits. | |
67 | // | |
68 | // Only one instance of this class is created in the macro: | |
a90ecf3c | 69 | // AliRunDigitizer * manager = |
70 | // new AliRunDigitizer(nInputStreams,SPERB); | |
71 | // where nInputStreams is number of input streams and SPERB is | |
72 | // signals per background variable, which determines how combinations | |
73 | // of signal and background events are generated. | |
9ce40367 | 74 | // Then instances of specific detector digitizers are created: |
75 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager) | |
a90ecf3c | 76 | // and the I/O configured (you have to specify input files |
77 | // and an output file). The manager connects appropriate trees from | |
78 | // the input files according a combination returned by AliMergeCombi | |
9ae76683 | 79 | // class. It creates TreeD in the output and runs once per |
a90ecf3c | 80 | // event Digitize method of all existing AliDetDigitizers |
81 | // (without any option). AliDetDigitizers ask manager | |
82 | // for a TTree with input (manager->GetInputTreeS(Int_t i), | |
9ce40367 | 83 | // merge all inputs, digitize it, and save it in the TreeD |
84 | // obtained by manager->GetTreeD(). Output events are stored with | |
85 | // numbers from 0, this default can be changed by | |
86 | // manager->SetFirstOutputEventNr(Int_t) method. The particle numbers | |
87 | // in the output are shifted by MASK, which is taken from manager. | |
88 | // | |
8d5e6345 | 89 | // The default output is to the signal file (stream 0). This can be |
90 | // changed with the SetOutputFile(TString fn) method. | |
91 | // | |
9ae76683 | 92 | // Single input file is permitted. Maximum kMaxStreamsToMerge can be merged. |
9ce40367 | 93 | // Input from the memory (on-the-fly merging) is not yet |
94 | // supported, as well as access to the input data by invoking methods | |
95 | // on the output data. | |
96 | // | |
a90ecf3c | 97 | // Access to the some data is via gAlice for now (supposing the |
98 | // same geometry in all input files), gAlice is taken from the first | |
99 | // input file on the first stream. | |
9ce40367 | 100 | // |
314558d7 | 101 | // Example with MUON digitizer, no merging, just digitization |
102 | // | |
103 | // AliRunDigitizer * manager = new AliRunDigitizer(1,1); | |
104 | // manager->SetInputStream(0,"galice.root"); | |
105 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager); | |
106 | // manager->Exec(""); | |
107 | // | |
108 | // Example with MUON digitizer, merge all events from | |
109 | // galice.root (signal) file with events from bgr.root | |
110 | // (background) file. Number of merged events is | |
111 | // min(number of events in galice.root, number of events in bgr.root) | |
112 | // | |
113 | // AliRunDigitizer * manager = new AliRunDigitizer(2,1); | |
114 | // manager->SetInputStream(0,"galice.root"); | |
115 | // manager->SetInputStream(1,"bgr.root"); | |
116 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager); | |
117 | // manager->Exec(""); | |
118 | // | |
119 | // Example with MUON digitizer, save digits in a new file digits.root, | |
120 | // process only 1 event | |
9ce40367 | 121 | // |
a90ecf3c | 122 | // AliRunDigitizer * manager = new AliRunDigitizer(2,1); |
