ImportWorkspaces

Import a RooFit workspace from a file with a given name. This must be a .root file.

Usage:

+ImportWorkspaces {
  +HWWRun2GGF{
    <inputFile = "./workspaces/run2-ggf-$(fitLabel)/workspace-preFit.root:HWWRun2GGF">
    <saveSnapshot="SnSh_AllVars_Nominal">
  }
}

This action supports a wealth of options to modify the workspace while loading.

• With saveSnasphot="somename", the initial configuration of the workspace can be saved as a snapshot.
• The following options can be used to edit the lists of nuisance parameters and parameters of interest:
  • removeNPs={"a","b",...}, addNPs={"a","b",...}
  • removePOIs={"a","b",...}, addPOIs={"a","b",...}
• The following options can be used to edit const/float properties of parameters:
  • constPars={"a","b",...}
  • floatPars={"a","b",...}
• The following options can be used to edit the values and errors of parameters
  • setPars.a=1.,setPars.b=2.
  • setParErrors.a=1.,setParErrors.b=1.
• By default, the workspace is re-generated to obtain a clean, in-memory variant, after which the input file is closed. This can be avoided and the in-file representation can be used by using the infile=true flag. Alternatively, the code can be instructed to instead of building a clean copy of the workspace just use the ROOT Streamer to clone the workspace including all its disconnected elements using the rebuild=false flag.
• The modelConfig option can be used to provide the name of the RooStats::ModelConfig object. This is required when the RooStats::ModelConfig in the workspace is not called "ModelConfig".
• The option clearSnapshots=true will not copy any snapshots into the in-memory representation into the workspace. Has no effect when infile=true is used.
