23// Clusterization class. Performs clusterization (collects neighbouring active cells) and
24// unfolds the clusters having several local maxima.
25// Results are stored in TreeR#, branches EMCALTowerRP (EMC recPoints),
26// EMCALPreShoRP (CPV RecPoints) and AliEMCALClusterizer (Clusterizer with all
27// parameters including input digits branch title, thresholds etc.)
28// This TTask is normally called from Reconstructioner, but can as well be used in
29// standalone mode.
30// Use Case:
31// root [0] AliEMCALClusterizerv1 * cl = new AliEMCALClusterizerv1("galice.root")
32// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
33// //reads gAlice from header file "..."
34// root [1] cl->ExecuteTask()
35// //finds RecPoints in all events stored in galice.root
36// root [2] cl->SetDigitsBranch("digits2")
37// //sets another title for Digitis (input) branch
38// root [3] cl->SetRecPointsBranch("recp2")
39// //sets another title four output branches
40// root [4] cl->SetTowerLocalMaxCut(0.03)
41// //set clusterization parameters
42// root [5] cl->ExecuteTask("deb all time")
43// //once more finds RecPoints options are
44// // deb - print number of found rec points
45// // deb all - print number of found RecPoints and some their characteristics
46// // time - print benchmarking results
