23 // Wrapping class for reconstruction. Allows to produce reconstruction from
24 // different steps: from previously produced hits,sdigits, etc. Each new reconstruction
25 // flow (e.g. digits, made from them RecPoints,
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
31 // TreeR::AliEMCALClusterizer with the same title as the branch containing the RecPoints. // TTree does not support overwriting, therefore one can not produce several
32 // branches with the same names and titles - use different titles.
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
41 // // One can specify the title for each branch
42 // root [2] r->SetBranchFileName("RecPoints","RecPoints1") ;
44 // // One can change parameters of reconstruction algorithms
45 // root [3] r->GetClusterizer()->SetEmcLocalMaxCut(0.02)
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,
51 // // and RecParticles
53 // // And finally one can call ExecuteTask() with the following options
54 // root [5] r->ExecuteTask("debug all timing")
55 // // deb - prints the numbers of RecPoints and RecParticles
56 // // deb all - prints in addition list of RecPoints and RecParticles
57 // // timing - prints benchmarking results
