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:
40// root [0] AliPHOSClusterizerv1 * cl = new AliPHOSClusterizerv1("galice.root")
41// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
9a1398dd 42// //reads gAlice from header file "..."
a4e98857 43// root [1] cl->ExecuteTask()
9a1398dd 44// //finds RecPoints in all events stored in galice.root
a4e98857 45// root [2] cl->SetDigitsBranch("digits2")
f035f6ce 46// //sets another title for Digitis (input) branch
a4e98857 47// root [3] cl->SetRecPointsBranch("recp2")
f035f6ce 48// //sets another title four output branches
a4e98857 49// root [4] cl->SetEmcLocalMaxCut(0.03)
9a1398dd 50// //set clusterization parameters
a4e98857 51// root [5] cl->ExecuteTask("deb all time")
9a1398dd 52// //once more finds RecPoints options are
53// // deb - print number of found rec points
54// // deb all - print number of found RecPoints and some their characteristics
55// // time - print benchmarking results
