Welcome to the wiki pages of the TauFW!

What is the TauFW ?

The TauFW is a framework developed for analysis of nanoAOD at CMS. The original purpose was to have a common framework for the TauPOG measurements in CMS that can run on common nanoAOD samples, and keep track of the scripts in this repository.

How do I install the TauFW ?

Please see the Installation page.

Where do I start?

Please have a look at our tutorial on lxplus: Quick start with TauFW

What does the TauFW offer ?

Three main packages are

1. PicoProducer:
   • Tools to run analysis code on nanoAOD for given lists of nanoAOD files.
   • Examples of ditau analysis code.
   • Tools to read & apply corrections in analyses (in particular for tau analysis at CMS).
   • Tools to keep track of nanoAOD samples stored on the GRID or other storage elements.
   • Tools to submit jobs to various batch systems. You can add your custom batch system as a module.
   • Tools to access various storage elements. You can add your custom storage system as a module.
2. Plotter:
   • Tools to plot histograms and data/MC comparisons in CMS style.
   • Tools to handle sets of samples and produces histograms (TH1) from analysis ntuples (TTree).
   • Tools for further analysis, auxiliary measurements, validation...
3. Fitter:
   • Tools for measurements and fits in combine.
   • [Under development.]

What are the TauFW's dependencies ?

PicoProducer:

• nanoAOD-tools is used by default for simple processing of nanoAOD. However, the TauFW tools should be able to run other nanoAOD processors like coffee.
• TauIDSFs for using corrections by the TauPOG.
• [under development] correctionlib to read JSON files (to replace TauIDSFs)

Plotter:

• ROOT for general plotting scripts
• [under development] ROOT v6.14 or newer for using RDataFrame to process custom ntuples.

Fitter:

• CMS's Combine tool
• CombineHarvester
