9a1398dd | 52 | // Clusterization class. Performs clusterization (collects neighbouring active cells) and |
a4e98857 | 53 | // unfolds the clusters having several local maxima. |
54 | // Results are stored in TreeR#, branches PHOSEmcRP (EMC recPoints), | |
9a1398dd | 55 | // PHOSCpvRP (CPV RecPoints) and AliPHOSClusterizer (Clusterizer with all |
f035f6ce | 56 | // parameters including input digits branch title, thresholds etc.) |
a4e98857 | 57 | // This TTask is normally called from Reconstructioner, but can as well be used in |
58 | // standalone mode. | |

fc12304f | 62 | // // reads gAlice from header file "galice.root", uses digits stored in the branch names "digitsname" (default = "Default") |
63 | // // and saves recpoints in branch named "recpointsname" (default = "digitsname") | |
a4e98857 | 64 | // root [1] cl->ExecuteTask() |
9a1398dd | 65 | // //finds RecPoints in all events stored in galice.root |
