9a1398dd 40// Clusterization class. Performs clusterization (collects neighbouring active cells) and
a4e98857 41// unfolds the clusters having several local maxima.
42// Results are stored in TreeR#, branches PHOSEmcRP (EMC recPoints),
9a1398dd 43// PHOSCpvRP (CPV RecPoints) and AliPHOSClusterizer (Clusterizer with all
f035f6ce 44// parameters including input digits branch title, thresholds etc.)
a4e98857 45// This TTask is normally called from Reconstructioner, but can as well be used in
46// standalone mode.
47// Use Case:
fc12304f 48// root [0] AliPHOSClusterizerv1 * cl = new AliPHOSClusterizerv1("galice.root", "recpointsname", "digitsname")
a4e98857 49// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
fc12304f 50// // reads gAlice from header file "galice.root", uses digits stored in the branch names "digitsname" (default = "Default")
51// // and saves recpoints in branch named "recpointsname" (default = "digitsname")
a4e98857 52// root [1] cl->ExecuteTask()
9a1398dd 53// //finds RecPoints in all events stored in galice.root
a4e98857 54// root [2] cl->SetDigitsBranch("digits2")
f035f6ce 55// //sets another title for Digitis (input) branch
a4e98857 56// root [3] cl->SetRecPointsBranch("recp2")
f035f6ce 57// //sets another title four output branches
a4e98857 58// root [4] cl->SetEmcLocalMaxCut(0.03)
9a1398dd 59// //set clusterization parameters
a4e98857 60// root [5] cl->ExecuteTask("deb all time")
9a1398dd 61// //once more finds RecPoints options are
62// // deb - print number of found rec points
63// // deb all - print number of found RecPoints and some their characteristics
64// // time - print benchmarking results
