9a1398dd 32// Clusterization class. Performs clusterization (collects neighbouring active cells) and
a4e98857 33// unfolds the clusters having several local maxima.
34// Results are stored in TreeR#, branches PHOSEmcRP (EMC recPoints),
9a1398dd 35// PHOSCpvRP (CPV RecPoints) and AliPHOSClusterizer (Clusterizer with all
f035f6ce 36// parameters including input digits branch title, thresholds etc.)
a4e98857 37// This TTask is normally called from Reconstructioner, but can as well be used in
38// standalone mode.
39// Use Case:
fc12304f 40// root [0] AliPHOSClusterizerv1 * cl = new AliPHOSClusterizerv1("galice.root", "recpointsname", "digitsname")
a4e98857 41// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
fc12304f 42// // reads gAlice from header file "galice.root", uses digits stored in the branch names "digitsname" (default = "Default")
43// // and saves recpoints in branch named "recpointsname" (default = "digitsname")
a4e98857 44// root [1] cl->ExecuteTask()
9a1398dd 45// //finds RecPoints in all events stored in galice.root
a4e98857 46// root [2] cl->SetDigitsBranch("digits2")
f035f6ce 47// //sets another title for Digitis (input) branch
a4e98857 48// root [3] cl->SetRecPointsBranch("recp2")
f035f6ce 49// //sets another title four output branches
a4e98857 50// root [4] cl->SetEmcLocalMaxCut(0.03)
9a1398dd 51// //set clusterization parameters
a4e98857 52// root [5] cl->ExecuteTask("deb all time")
9a1398dd 53// //once more finds RecPoints options are
54// // deb - print number of found rec points
55// // deb all - print number of found RecPoints and some their characteristics
56// // time - print benchmarking results
