3 | * Example macro to run the Offline ITS Cluster Finding in HLT. | |
4 | * The reconstruction is done from the ITS raw data. | |
5 | * | |
6 | * Usage: | |
7 | * <pre> | |
8 | * aliroot -b -q rec-its-cluster.C | tee rec-its-cluster.log | |
9 | * aliroot -b -q rec-its-cluster.C'("./","spd")' | tee rec-its-cluster.log | |
10 | * </pre> | |
11 | * | |
12 | * The macro asumes raw data to be available in the rawx folders, either | |
13 | * simulated or real data. A different input can be specified as parameter | |
14 | * <pre> | |
15 | * aliroot -b -q rec-its-cluster.C'("input.root")' | |
16 | * </pre> | |
17 | * | |
18 | * In the second parameter you can change the clusterfinders to run only | |
19 | * SPD, SDD, SSD or All: | |
20 | * - SPD runs only Silicon Pixels | |
21 | * - SDD runs only Silicon Drift | |
22 | * - SSD runs only Silicon Stips | |
23 | * - All will run the full ITS | |
24 | * | |
25 | * All is default. The chain ends in a histogram component. | |
26 | * | |
27 | * The reconstruction is steered by the AliReconstruction object in the | |
28 | * usual way. | |
