Production to merge histograms are slightly different from normal data processing ones. There are two different type of input files to consider: BRUNELHIST and DAVINCIHIST, so in the Input Data section of the request, it must be selected both file types.

  • Screenshot of the Histo Merging request:

The template to choose is Type HistoMerge as production to be launched, GroupSize must be equal to 999999, as we create one single merged file per run. Output Data Storage Element must be CERN-HIST-EOS. The plugin name must be ByRunSizeWithFlushRootMerging and the removeInputs flag must be set to True in order to delete the unmerged files.
