3 * Example macro to run locally an analysis task for comparing the offline
4 * with the HLT esd tree.
6 * The output is a root file containing the objects defined in the
7 * analysis task. These could be histograms or THnSparse objects.
8 * There is one output file per task containing a TList of TH1 or THnSparse objects.
10 * Run without arguments to get a few examples how to use the macro
11 * and which tasks are available in svn.
14 * - the input file or txt file containing a list of ESDs to be processed (CreateESDChain takes 20 files as a default argument)
15 * - the task you want to use
16 * - the path of the task location
17 * - the beam type, "p-p" or "Pb-Pb", this is relevant for the central barrel and global tasks at the moment and is
18 * used to select proper binning and axes ranges for the THnSparse/TH1 objects that it fills
19 * - options to make the central barrel task more flexible and lightweight; you can select if you want to
20 * fill the THnSparse object with only event or track properties or only HLT data or only OFF
21 * possible options are: event-off event-hlt track-off track-hlt, all are turned on by default
22 * - boolean variable for selecting events which contain an HLT trigger
23 * - number of events to be analyzed
25 * If alien:// is placed before the input filename, then the macro connects to the grid to access the file.
27 * In case you want to run over many ESD files, then prepare a list of them in a .txt file and they will be chained for the analysis.
28 * The .txt file takes the place of the first argument in that case. The chain can take up to 200 files at the moment. The user
29 * can modify this in the call CreateESDChain(file.Data(),200);
31 * If the files are not sitting locally but on the GRID, then their location should be designated like:
32 * alien:///alice/data/2011/LHC11a/000146018/ESDs/pass1/11000146018023.20/AliESDs.root in the *txt file.
33 * The macro takes care of connecting to the GRID, as soon as the first file is found that begins with alien://
