Skip running on gen information for data

[ram1123]

Currently, this code also looks for generator information in the data, which is not there. Need to fix.

More information

• In data, we don't have generator-level information.

• If you pick a data root file and try to run. Then, the code will try to find the generator-level information in the data root file, which is not there. And then it will, through error, say that no branch exists.

Possible solution

• Utilize the variable isMCTrueFalse defined in post-proc (its better to rename isMCTrueFalse -> isMC): https://github.com/ram1123/nanoAOD_skim/blob/7e7653dc68018f2cb5a7d4fb7e6c843fe19f7ae3/post_proc.py#L40

  and pass it to module HZZAnalysisCppProducer. Furthermore it would be good if it does this automatically. It can be achieved like:

  if testfilelist[0].find("\data\") != -1: isMC = False

• Then use this to skip all gen related part. something like this:

  if (isMC):
    genparts = Collection(event, "GenPart")
  
  if (ifMC):
      for xg in genparts:
          self.worker.SetGenParts(xg.pt)
