4 | * @brief Detector reconstruction from HLTOUT data | |
5 | * | |
6 | * Example macro to run detector reconstruction from the HLTOUT data | |
7 | * instead of the original detector data. | |
8 | * | |
9 | * Usage: aliroot -b -q rec-from-hltout.C | tee rec-from-hltout.log | |
10 | * | |
11 | * The macro asumes detector ddl raw data to be available in the HLTOUT, | |
12 | * e.g. simulated by sim-hlt-rawddl.C | |
13 | * Input replacement is run for the ITS (Note that only the ITSSDD was | |
14 | * published to HLTOUT) | |
15 | * | |
16 | * The HLTOUT handler implemented in libAliHLTSample.lib is used to | |
17 | * redirect data blocks of type {DDLRAW :SMPL} from the HLTOUT to the | |
18 | * reconstruction input. \b Note: the origin \em SMPL is a special | |
19 | * id just for the purpose of examples. | |
