11 | * Run second pass analysis - make @f$ dN/d\eta@f$ | |
12 | * | |
13 | * If the ROOT AliEn interface library (libRAliEn) can be loaded, | |
14 | * and the parameter @a name is not empty, then use the plugin to do | |
15 | * the analysis. Note that in this case, the output is placed | |
16 | * in a sub-directory named by @a name after escaping spaces and special | |
17 | * characters | |
18 | * | |
19 | * @param aoddir AOD input directory. Any file matching the pattern | |
20 | * *AliAODs*.root are added to the chain | |
21 | * @param nEvents Number of events to process. If 0 or less, then | |
22 | * all events are analysed | |
23 | * @param trig Trigger to use | |
24 | * @param useCent Whether to use centrality or not | |
25 | * @param scheme Normalisation scheme | |
26 | * @param vzMin Least @f$ v_z@f$ (centimeter) | |
27 | * @param vzMax Largest @f$ v_z@f$ (centimeter) | |
28 | * @param proof If larger then 1, run in PROOF-Lite mode with this | |
29 | * many number of workers. | |
30 | * @param name Name of train - free form. This will be the name | |
31 | * of the output directory if the plug-in is used | |
