19// Implementation of the TPC clusterer
20//
ebe95b38 21// 1. The Input data for reconstruction - Options
22// 1.a Simulated data - TTree - invoked Digits2Clusters()
23// 1.b Raw data - Digits2Clusters(AliRawReader* rawReader);
24//
25// 2. The Output data
26// 2.a TTree with clusters - if SetOutput(TTree * tree) invoked
27// 2.b TObjArray - Faster option for HLT
98ee6d31 28// 2.c TClonesArray - Faster option for HLT (smaller memory consumption), activate with fBClonesArray flag
ebe95b38 29//
30// 3. Reconstruction setup
31// see AliTPCRecoParam for list of parameters
32// The reconstruction parameterization taken from the
33// AliTPCReconstructor::GetRecoParam()
34// Possible to setup it in reconstruction macro AliTPCReconstructor::SetRecoParam(...)
35//
