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(...) | |
