* Example macro to run locally an analysis task for comparing the offline
* with the HLT esd tree.
*
- * The output is a root file containing the histograms defined in the
- * analysis task. There is one output file per detector.
+ * The output is a root file containing the objects defined in the
+ * analysis task. These could be histograms or THnSparse objects.
+ * There is one output file per task containing a TList of TH1 or THnSparse objects.
*
- * Run without arguments to get a few examples how to use the macro.
+ * Run without arguments to get a few examples how to use the macro
+ * and which tasks are available in svn.
*
* The arguments are:
* - the input file or txt file containing a list of ESDs to be processed (CreateESDChain takes 20 files as a default argument)
* If alien:// is placed before the input filename, then the macro connects to the grid to access the file.
*
* 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.
- * The .txt file takes the place of the first argument in that case.
+ * 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
+ * can modify this in the call CreateESDChain(file.Data(),200);
+ *
+ * If the files are not sitting locally but on the GRID, then their location should be designated like:
+ * alien:///alice/data/2011/LHC11a/000146018/ESDs/pass1/11000146018023.20/AliESDs.root in the *txt file.
+ * The macro takes care of connecting to the GRID, as soon as the first file is found that begins with alien://
