2e3dd5e5 | 18 | Revision 1.16 2002/06/07 09:18:47 jchudoba |
19 | Changes to enable merging of ITS fast rec points. Although this class should be responsible for a creation of digits only, other solutions would be more complicated. | |
20 | ||
a08ddb28 | 21 | Revision 1.15 2002/04/09 13:38:47 jchudoba |
22 | Add const to the filename argument | |
23 | ||
3466e07f | 24 | Revision 1.14 2002/04/04 09:28:04 jchudoba |
25 | 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. | |
26 | ||
9b31ff31 | 27 | Revision 1.13 2002/02/13 09:03:32 jchudoba |
28 | 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. | |
29 | ||
f042097d | 30 | Revision 1.12 2001/12/10 16:40:52 jchudoba |
31 | Import gAlice from the signal file before InitGlobal() to allow detectors to use it during initialization | |
32 | ||
7e68127f | 33 | Revision 1.11 2001/12/03 07:10:13 jchudoba |
34 | 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 | |
35 | ||
314558d7 | 36 | Revision 1.10 2001/11/15 11:07:25 jchudoba |
37 | 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. | |
38 | ||
9ae76683 | 39 | Revision 1.9 2001/11/15 09:00:11 jchudoba |
40 | Add special treatment for TPC and TRD, they use different trees than other detectors | |
41 | ||
f34e67f9 | 42 | Revision 1.8 2001/10/21 18:38:43 hristov |
43 | Several pointers were set to zero in the default constructors to avoid memory management problems | |
44 | ||
2685bf00 | 45 | Revision 1.7 2001/10/04 15:56:07 jchudoba |
46 | TTask inheritance | |
47 | ||
bd7a3098 | 48 | Revision 1.4 2001/09/19 06:23:50 jchudoba |
49 | Move some tasks to AliStream and AliMergeCombi classes | |
50 | ||
a90ecf3c | 51 | Revision 1.3 2001/07/30 14:04:18 jchudoba |
52 | correct bug in the initialization | |
53 | ||
af20391f | 54 | Revision 1.2 2001/07/28 10:44:32 hristov |
55 | Loop variable declared once; typos corrected | |

66 | // Manager object for merging/digitization | |
67 | // | |
68 | // Instance of this class manages the digitization and/or merging of | |
69 | // Sdigits into Digits. | |
70 | // | |
71 | // Only one instance of this class is created in the macro: | |
a90ecf3c | 72 | // AliRunDigitizer * manager = |
73 | // new AliRunDigitizer(nInputStreams,SPERB); | |
74 | // where nInputStreams is number of input streams and SPERB is | |
75 | // signals per background variable, which determines how combinations | |
76 | // of signal and background events are generated. | |
9ce40367 | 77 | // Then instances of specific detector digitizers are created: |
78 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager) | |
a90ecf3c | 79 | // and the I/O configured (you have to specify input files |
80 | // and an output file). The manager connects appropriate trees from | |
81 | // the input files according a combination returned by AliMergeCombi | |
9ae76683 | 82 | // class. It creates TreeD in the output and runs once per |
a90ecf3c | 83 | // event Digitize method of all existing AliDetDigitizers |
84 | // (without any option). AliDetDigitizers ask manager | |
85 | // for a TTree with input (manager->GetInputTreeS(Int_t i), | |
9ce40367 | 86 | // merge all inputs, digitize it, and save it in the TreeD |
87 | // obtained by manager->GetTreeD(). Output events are stored with | |
88 | // numbers from 0, this default can be changed by | |
89 | // manager->SetFirstOutputEventNr(Int_t) method. The particle numbers | |
90 | // in the output are shifted by MASK, which is taken from manager. | |
91 | // | |
8d5e6345 | 92 | // The default output is to the signal file (stream 0). This can be |
93 | // changed with the SetOutputFile(TString fn) method. | |
94 | // | |
9ae76683 | 95 | // Single input file is permitted. Maximum kMaxStreamsToMerge can be merged. |
9ce40367 | 96 | // Input from the memory (on-the-fly merging) is not yet |
97 | // supported, as well as access to the input data by invoking methods | |
98 | // on the output data. | |
99 | // | |
a90ecf3c | 100 | // Access to the some data is via gAlice for now (supposing the |
101 | // same geometry in all input files), gAlice is taken from the first | |
102 | // input file on the first stream. | |
9ce40367 | 103 | // |
314558d7 | 104 | // Example with MUON digitizer, no merging, just digitization |
105 | // | |
106 | // AliRunDigitizer * manager = new AliRunDigitizer(1,1); | |
107 | // manager->SetInputStream(0,"galice.root"); | |
108 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager); | |
109 | // manager->Exec(""); | |
110 | // | |
111 | // Example with MUON digitizer, merge all events from | |
112 | // galice.root (signal) file with events from bgr.root | |
113 | // (background) file. Number of merged events is | |
114 | // min(number of events in galice.root, number of events in bgr.root) | |
115 | // | |
116 | // AliRunDigitizer * manager = new AliRunDigitizer(2,1); | |
117 | // manager->SetInputStream(0,"galice.root"); | |
118 | // manager->SetInputStream(1,"bgr.root"); | |
119 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager); | |
120 | // manager->Exec(""); | |
121 | // | |
122 | // Example with MUON digitizer, save digits in a new file digits.root, | |
123 | // process only 1 event | |
9ce40367 | 124 | // |
a90ecf3c | 125 | // AliRunDigitizer * manager = new AliRunDigitizer(2,1); |
