CombineWorkspaces

Combine several workspaces to a combined measurement.

Usage:

+CombineWorkspaces {
  +HWWRun2 {
    <verbose=true,asimov=false>
    <correlationSchemes = {
      "config/statistics/comb/snippets/correlations.ggF.txt",
      "config/statistics/comb/snippets/correlations.vbf.txt"
    }>
    +HWWRun2GGF {
      <SnapshotName="SnSh_AllVars_Nominal",DataName="obsData">
    }
    +HWWRun2VBF {
      <SnapshotName="NominalParamValues",DataName="obsData">
    }
    <BinnedLikelihood=true> @ ?;
  }
}

This Action internally uses the RooFitUtils extension package and will fail with a runtime error if that is not present. Options include:

• correlationSchemes: List of correlation schemes. These are text files with lines in the format

  WorkspaceName::OldParameterName>>NewParameterName
  

  These define which parameters from which workspaces should be correlated with each other by renaming them.
• autocorrelation: Set to true to auto-correlate all parameters with the same name from different input workspaces.
• verbose: Set to true to get verbose output.
• asimov: Set to true to generate an asimov dataset on the output workspace.
• writeTable: Provide a file name to write a table of which parameters were correlated in the end. Each workspace to be combined should be provided as one subfolder. Options on the input workspaces include
• SnapshotName: Set the Snapshot name to be loaded before combining.
• DataName: Set the name of the dataset the be used for the combination.
• BinnedLikelihood: Activate BinnedLikelihood for the input measurement.
