How to build ROOT with CVMFS on CentOS 7
=========================================

For profiling with debug symbols or just to test the newest ROOT features, you may want to use your own ROOT version. Here are the commands, which allow you to build ROOT with a given build type, ROOT release tag and C++ 17.

Most likely, you want to use :code:`RelWithDebInfo` as build type so you get debug symbols but also a realistic performance due to compiler optimizations.

May 2024 - Version 0.4.0

* Switch to ROOT 6.30, supporting now RHEL8 and RHEL9.
* Introduced support for ML inference via `OnnxRuntime`. A generic producer is avialable at this link: https://github.com/KIT-CMS/CROWN/blob/main/include/ml.hxx
* Introduced a CorrectionManager, that is responsible for loading correction files and sharing them among the different producers. This allows to load the corrections only once and share them among the different producers, resulting in a signifiant speedup of the initial loading time. In the course of this implementation, Many functions now have a deprecated version, that does not use the `CorrectionManager`. The old functions will be removed in the next release. A more detailed description can be found in the :ref:`The Correction Manager` page.

Writing a new producer

Writing a new producer involves two main parts, adding the :ref:`C++ function<Writing a new C++ function>` and the required :ref:`python component<Defining a new python Producer>`.

If the C++ function is written generically enough, it can be used in multiple producers and multiple purposes in the end.
For example, the producer generating the pt_1 quantity can be used regardless of what particle is being considered.

In the following, an introduction on how to add a new producer is given. As an example, we will add a new producer, which can be used to calculate the Lorentz vectors of particles, in our case electrons. For simplicity, we only want to calculate one single Lorentz vector for a given index. First, we will do the C++ implementation of the function followed by the Python definition. Keep in mind, that those two parts are connected.

Writing a new C++ function
============================

For a new C++ function, a definition in the header file, and the implementation in the source file are required. As good practice, we will add the function to a namespace called ``lorentzvector``, and call the function ``build``.
The return type of any function in CROWN should always be ``ROOT::RDF::RNode`` and the first argument of the function should always be the RDataframe, where we want to Define our new quantity. This means the basic definition of the function should look like this:

FriendTree Generation
===========================

CROWN can be used, to generate FriendTrees based on a CROWN ntuple. The concept of FriendTrees is explained here: https://root.cern/manual/trees/#widening-a-ttree-through-friends. They allow to extend an existing ntuple with new quantities. Common use cases are new high-level variables like neural network outputs or additional correction factors.

The the example depicted above, two additional friends to the main NTuple are created. During analysis, the quantities stored in the friend trees can be added by using the ``AddFriend`` method. The quantities are then available in the TTree as if they were part of the original NTuple.

A FriendTree is generated using a FriendTreeConfiguration. Such a configuration has some major differences, compared to a regular configuration:

2. Only one scope per user is allowed.
3. No global scope is required
4. The available inputs have to be specified. The available inputs can be provided by using a CROWN ntuple as input, or a JSON file. The ntuple can be used for debugging proposes, when running a production, it is recommended to use a JSON file. The basic structure of this quantities map is listed below. Such a JSON can then be used for multiple eras, sample types and scopes.

All other parameters are identical to the regular configuration. Setting up producers, outputs and new systematic shifts works the same way as before.

In addition, as for CROWN ntuples, only required shifts are executed.

FriendTrees with multiple input friend trees
--------------------------------------------

Starting from version 0.3 of CROWN, it is also possible to use multiple input friend trees. A typical use case for this feature is the evaluation of Classifiers, and storing the output of the classifier in the friend tree. This way, the classifier can utilize quantities from both the main ntuple and from additional friend trees. The interface for configuring such a FriendTree executable is similar to the regular FriendTree configuration, with the following differences:

Introduction
=============

The **C** ++-based **RO** OT **W** orkflow for **N** -tuples (CROWN) is a fast new way to convert NanoAOD samples into flat :code:`TTrees` to be used in further analysis. The main focus of the framework is to provide a fast and clean way of selecting events and calculating quantities and weights. The framework has minimal dependencies and only uses ROOT and it's Dataframe as a backend.

Ntuples in Postprocessing
===========================

The CROWN Ntuples can be used by any Postprocessing framework. Some things have to be kept in mind, in order to ensure an easy processing.
Most important difference is, that only quantities affected by a shift are recalculated. This means the prostprocessing framework must be able to use a mixture of the original and the shifted quantities, when applying shifts. In order to make this step a bit easier, the information, which quantities are affected by a shift, is stored in the Ntuple.

Quantity mapping
*****************

To read the mapping from a NTuple, the python function listed below may be used. Two types of mapping are available, depending on the actual usecase. In the first, the mapping is sorted by shift; in the second the mapping is sorted by quantity.
