As of 2024-10-14, TrkAna has now been replaced by [[EventNtuple]]. This page is just being kept for archival purposes.
== Overview ==
== Overview ==
TrkAna is a track-based ROOT TTree that can be used to help with analysis. Each entry in the TTree corresponds to a single fitted track and contains reconstructed information from the tracker, calorimeter and CRV. There is also the option to write out Monte Carlo truth information and additional information for other track types that might be important to an analysis.

Feel free to send any questions to the [https://mu2e.slack.com/archives/C023EVADW2X #trkana] or #is_it_me_or_a_bug Slack channels
 
There is a tutorial hosted in the [https://github.com/Mu2e/TrkAna/blob/main/tutorial/README.md GitHub respository].
 
== For Analyzers ==
=== How to Analyze a TrkAna Tree ===
'''Updated: 2024-06-21'''


There is a [https://mu2ewiki.fnal.gov/wiki/TrkAna_Tutorial_Session tutorial] and a hypernews forum you can sign up to.
See the tutorials on GitHub here: https://github.com/Mu2e/TrkAna/blob/main/tutorial/README.md for exercises that analyze TrkAna trees with both ROOT and python


== How To Run ==
=== How To Create a TrkAna Tree ===
There is an example fcl configuration in the Offline repository that runs on [https://mu2ewiki.fnal.gov/wiki/MDC2018#Reco_Datasets reco datasets].
'''Updated: 2024-06-21'''


<code>mu2e -c TrkDiag/fcl/TrkAnaReco.fcl -s mcs.art --TFileName trkana.root</code>
You can use the TrkAna Musing like so:
<pre>
mu2einit
muse setup TrkAna
mu2e -c TrkAna/fcl/TrkAnaReco.fcl -s mcs.art --TFileName trkana.root
</pre>


This runs two instances of the TrackAnalysisReco module. One for negative tracks (TrkAnaNeg) and one for positive tracks (TrkAnaPos). Each tree has the same structure has shown below.
where mcs.art contains the result of the Mu2e reconstruction.
 
In the trkana.root file, you will find the TrkAna TTree in <pre>TrkAna/trkana</pre>.
 
TrkAna is designed to have some flexibility. There are fcl parameters that can be changed and there are a few examples available here: https://github.com/Mu2e/TrkAna/tree/main/fcl and are given in the table below in [[#TrkAna Fcl Examples]]. Also, you can always ask for help on the #trkana channel on Slack
 
== For Developers ==
'''Updated: 2024-06-17'''
 
If you will be contributing to the development of TrkAna, then you should fork TrkAna on GitHub into your GitHub account, and then set up your development area like so:
 
Once you log in:
<pre>
mu2einit
cd /your/working/directory
muse backing HEAD
git clone git@github.com:<Your GitHub Username>/TrkAna.git
 
cd TrkAna
git remote -f add mu2e https://github.com/Mu2e/TrkAna # add the main Mu2e/TrkAna repository as a remote
git fetch mu2e main # grab the current HEAD of Mu2e/TrkAna
git checkout --no-track -b <name-of-your-dev-branch> mu2e/main # create a branch from the HEAD of Mu2e/TrkAna
 
muse setup
muse build -j4 --mu2eCompactPrint
</pre>
 
Then you can make your developments (git commit, git push etc.) and then put in a pull request on GitHub.

== Tree Structure ==
== Tree Structure ==
Here is a very rough description of the tree branches and where to find leaf definitions in the repository:
The TrkAna tree structure is documented in google sheet (spreadsheet).  There are separate sheets for different major version numbers.
Links to the existing sheets are below.  These are viewable by anyone; if you would like to comment or edit these sheets please
send a message to the [https://mu2e.slack.com/archives/C023EVADW2X #TrkAna slack channel].
Note that the sheets have multiple tabs, at the bottom of the page. The main tab lists the branches, while the other tabs list
the detailed content (leafs) of the individual branches, by name.

== Hit Level Information ==
By setting the <code>diagLevel</code> to 2 when running TrkAna, you will fill hit level information branches.
If you are processing Monte Carlo information, hit level Monte Carlo truth branches will also be added.
Adding these increases the size of the output file by an order of magnitude.

TrkAna is now obsolete!

As of 2024-10-14, TrkAna has now been replaced by EventNtuple. This page is just being kept for archival purposes.

Overview

Updated: 2024-06-21

TrkAna is an event-based ROOT TTree that can be used for analysis. Each entry in the TTree corresponds to a single Mu2e event and contains reconstructed information from the tracker, calorimeter and CRV. There is also the option to write out Monte Carlo truth information and hit-level information.

How to Get Help

Updated: 2024-06-21

Feel free to send any questions to the #trkana or #is_it_me_or_a_bug Slack channels

There is a tutorial hosted in the GitHub respository.

For Analyzers

How to Analyze a TrkAna Tree

Updated: 2024-06-21

See the tutorials on GitHub here: https://github.com/Mu2e/TrkAna/blob/main/tutorial/README.md for exercises that analyze TrkAna trees with both ROOT and python

How To Create a TrkAna Tree

Updated: 2024-06-21

You can use the TrkAna Musing like so: 

mu2einit
muse setup TrkAna
mu2e -c TrkAna/fcl/TrkAnaReco.fcl -s mcs.art --TFileName trkana.root

where mcs.art contains the result of the Mu2e reconstruction.

In the trkana.root file, you will find the TrkAna TTree in 

TrkAna/trkana

.

TrkAna is designed to have some flexibility. There are fcl parameters that can be changed and there are a few examples available here: https://github.com/Mu2e/TrkAna/tree/main/fcl and are given in the table below in #TrkAna Fcl Examples. Also, you can always ask for help on the #trkana channel on Slack

For Developers

Updated: 2024-06-17

If you will be contributing to the development of TrkAna, then you should fork TrkAna on GitHub into your GitHub account, and then set up your development area like so:

Once you log in: 

mu2einit
cd /your/working/directory
muse backing HEAD
git clone git@github.com:<Your GitHub Username>/TrkAna.git

cd TrkAna
git remote -f add mu2e https://github.com/Mu2e/TrkAna # add the main Mu2e/TrkAna repository as a remote
git fetch mu2e main # grab the current HEAD of Mu2e/TrkAna
git checkout --no-track -b <name-of-your-dev-branch> mu2e/main # create a branch from the HEAD of Mu2e/TrkAna

muse setup
muse build -j4 --mu2eCompactPrint

Then you can make your developments (git commit, git push etc.) and then put in a pull request on GitHub.
