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