19 | // Options for the TPC Reconstruction in rec.C | |
20 | // | |
21 | // 4 options can be set to change the input for TPC reconstruction | |
22 | // which overwrites the usage of fUseHLTClusters of the AliTPCRecoParam | |
23 | // | |
24 | // 1) useRAW - use RAW, if not present -> do nothing | |
25 | // 2) useRAWorHLT - use RAW, if not present -> use HLT clusters | |
26 | // 3) useHLT - use HLT clusters, if not present -> do nothing | |
27 | // 4) useHLTorRAW - use HLT clusters, if not present -> use RAW | |
28 | // | |
29 | // -> The current default is useHLTorRAW | |
