23 | // Wrapping class for reconstruction. Allows to produce reconstruction from | |
24 | // different steps: from previously produced hits,sdigits, etc. Each new reconstruction | |
d018ba66 | 25 | // flow (e.g. digits, made from them RecPoints, |
6ddf6724 | 26 | // subsequently made RecParticles) are distinguished by the title of created branches. One can |
27 | // use this title as a comment, see use case below. | |
28 | // Thanks to getters, one can set | |
29 | // parameters to reconstruction briks. The full set of parameters is saved in the | |
30 | // corresponding branch: e.g. parameters of clusterizer are stored in branch | |
d018ba66 | 31 | // TreeR::AliEMCALClusterizer with the same title as the branch containing the RecPoints. // TTree does not support overwriting, therefore one can not produce several |
6ddf6724 | 32 | // branches with the same names and titles - use different titles. |
33 | // | |
34 | // Use case: | |
35 | // | |
36 | // root [0] AliEMCALReconstructioner * r = new AliEMCALReconstructioner("galice.root") | |
37 | // // Set the header file | |
38 | // root [1] r->ExecuteTask() | |
39 | // // Make full chain of reconstruction | |
40 | // | |
41 | // // One can specify the title for each branch | |
42 | // root [2] r->SetBranchFileName("RecPoints","RecPoints1") ; | |
43 | // | |
44 | // // One can change parameters of reconstruction algorithms | |
45 | // root [3] r->GetClusterizer()->SetEmcLocalMaxCut(0.02) | |
46 | // | |
47 | // // One can specify the starting point of the reconstruction and title of all | |
48 | // // branches produced in this pass | |
49 | // root [4] r->StartFrom("AliEMCALClusterizer","Local max cut 0.02") | |
50 | // // means that will use already generated Digits and produce only RecPoints, | |
d018ba66 | 51 | // // and RecParticles |
6ddf6724 | 52 | // |
53 | // // And finally one can call ExecuteTask() with the following options | |
54 | // root [5] r->ExecuteTask("debug all timing") | |
85ef0957 | 55 | // // deb - prints the numbers of RecPoints and RecParticles |
56 | // // deb all - prints in addition list of RecPoints and RecParticles | |
6ddf6724 | 57 | // // timing - prints benchmarking results |
