b9d0a01d | 18 | Revision 1.13.6.2 2002/07/24 10:08:13 alibrary |
19 | Updating VirtualMC | |
20 | ||
21 | Revision 1.19 2002/07/19 12:46:05 hristov | |
22 | Write file instead of closing it | |
23 | ||
3c2f4fb2 | 24 | Revision 1.18 2002/07/17 08:59:39 jchudoba |
25 | Do not delete subtasks when AliRunDigitizer is deleted. Owner should delete them itself. | |
26 | ||
1c16a4ba | 27 | Revision 1.17 2002/07/16 13:47:53 jchudoba |
28 | Add methods to get access to names of files used in merging. | |
29 | ||
2e3dd5e5 | 30 | Revision 1.16 2002/06/07 09:18:47 jchudoba |
31 | 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. | |
32 | ||
a08ddb28 | 33 | Revision 1.15 2002/04/09 13:38:47 jchudoba |
34 | Add const to the filename argument | |
35 | ||
3466e07f | 36 | Revision 1.14 2002/04/04 09:28:04 jchudoba |
37 | 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. | |
38 | ||
9b31ff31 | 39 | Revision 1.13 2002/02/13 09:03:32 jchudoba |
40 | 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. | |
41 | ||
f042097d | 42 | Revision 1.12 2001/12/10 16:40:52 jchudoba |
43 | Import gAlice from the signal file before InitGlobal() to allow detectors to use it during initialization | |
44 | ||
7e68127f | 45 | Revision 1.11 2001/12/03 07:10:13 jchudoba |
46 | 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 | |
47 | ||
314558d7 | 48 | Revision 1.10 2001/11/15 11:07:25 jchudoba |
49 | 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. | |
50 | ||
9ae76683 | 51 | Revision 1.9 2001/11/15 09:00:11 jchudoba |
52 | Add special treatment for TPC and TRD, they use different trees than other detectors | |
53 | ||
f34e67f9 | 54 | Revision 1.8 2001/10/21 18:38:43 hristov |
55 | Several pointers were set to zero in the default constructors to avoid memory management problems | |
56 | ||
2685bf00 | 57 | Revision 1.7 2001/10/04 15:56:07 jchudoba |
58 | TTask inheritance | |
59 | ||
bd7a3098 | 60 | Revision 1.4 2001/09/19 06:23:50 jchudoba |
61 | Move some tasks to AliStream and AliMergeCombi classes | |
62 | ||
a90ecf3c | 63 | Revision 1.3 2001/07/30 14:04:18 jchudoba |
64 | correct bug in the initialization | |
65 | ||
af20391f | 66 | Revision 1.2 2001/07/28 10:44:32 hristov |

78 | // Manager object for merging/digitization | |
79 | // | |
80 | // Instance of this class manages the digitization and/or merging of | |
81 | // Sdigits into Digits. | |
82 | // | |
83 | // Only one instance of this class is created in the macro: | |
a90ecf3c | 84 | // AliRunDigitizer * manager = |
85 | // new AliRunDigitizer(nInputStreams,SPERB); | |
86 | // where nInputStreams is number of input streams and SPERB is | |
87 | // signals per background variable, which determines how combinations | |
88 | // of signal and background events are generated. | |
9ce40367 | 89 | // Then instances of specific detector digitizers are created: |
90 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager) | |
a90ecf3c | 91 | // and the I/O configured (you have to specify input files |
92 | // and an output file). The manager connects appropriate trees from | |
93 | // the input files according a combination returned by AliMergeCombi | |
9ae76683 | 94 | // class. It creates TreeD in the output and runs once per |
a90ecf3c | 95 | // event Digitize method of all existing AliDetDigitizers |
96 | // (without any option). AliDetDigitizers ask manager | |
97 | // for a TTree with input (manager->GetInputTreeS(Int_t i), | |
9ce40367 | 98 | // merge all inputs, digitize it, and save it in the TreeD |
99 | // obtained by manager->GetTreeD(). Output events are stored with | |
100 | // numbers from 0, this default can be changed by | |
101 | // manager->SetFirstOutputEventNr(Int_t) method. The particle numbers | |
102 | // in the output are shifted by MASK, which is taken from manager. | |
103 | // | |
8d5e6345 | 104 | // The default output is to the signal file (stream 0). This can be |
105 | // changed with the SetOutputFile(TString fn) method. | |
106 | // | |
9ae76683 | 107 | // Single input file is permitted. Maximum kMaxStreamsToMerge can be merged. |
9ce40367 | 108 | // Input from the memory (on-the-fly merging) is not yet |
109 | // supported, as well as access to the input data by invoking methods | |
110 | // on the output data. | |
111 | // | |
a90ecf3c | 112 | // Access to the some data is via gAlice for now (supposing the |
113 | // same geometry in all input files), gAlice is taken from the first | |
114 | // input file on the first stream. | |
9ce40367 | 115 | // |
314558d7 | 116 | // Example with MUON digitizer, no merging, just digitization |
117 | // | |
118 | // AliRunDigitizer * manager = new AliRunDigitizer(1,1); | |
119 | // manager->SetInputStream(0,"galice.root"); | |
120 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager); | |
121 | // manager->Exec(""); | |
122 | // | |
123 | // Example with MUON digitizer, merge all events from | |
124 | // galice.root (signal) file with events from bgr.root | |
125 | // (background) file. Number of merged events is | |
126 | // min(number of events in galice.root, number of events in bgr.root) | |
127 | // | |
128 | // AliRunDigitizer * manager = new AliRunDigitizer(2,1); | |
129 | // manager->SetInputStream(0,"galice.root"); | |
130 | // manager->SetInputStream(1,"bgr.root"); | |
131 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager); | |
132 | // manager->Exec(""); | |
133 | // | |
134 | // Example with MUON digitizer, save digits in a new file digits.root, | |
135 | // process only 1 event | |
9ce40367 | 136 | // |
a90ecf3c | 137 | // AliRunDigitizer * manager = new AliRunDigitizer(2,1); |
