PTD2Root

A simple Falaise plugin to convert BRIO format particle tracking data to a flat ROOT TTree

Installing

PTD2Root requires the following software:

• CMake 3.3 or higher
• Falaise 2.0 or higher
  • Falaise will provide the needed Bayeux and ROOT dependencies

These packages can easily be obtained through the cadfaelbrew package manager. PTD2Root is also supplied through this system, so if you have this installed, simply do

$ brew install ptd2root

To build and install from source, simply do:

$ git clone https://github.com/SuperNEMO-DBD/PTD2Root.git PTD2Root.git
$ cd PTD2Root.git
$ ls
CMakeLists.txt flptd2root.py  p2r.conf       ptd2root.cpp   ptd2root.h     readme.pdf
$ mkdir build
$ cd build
$ cmake ..
$ make && make install

Using the Converter

Both a plugin module for Falaise's flreconstruct program is supplied, together with a convenience command-line converter program.

If you already have BRIO output files from flreconstruct, these can be converted to ROOT TTree format using the flptd2root.py program. This may be passed the name of the input BRIO file and desired output ROOT file, e.g.

$ flptd2root.py -i mybriofile.brio -o converted.root

Note that flptd2root.py requires the flreconstruct program to be in your PATH.

To use the plugin module in your own pipeline, simply add it as the last step. The output file can be set with the filename_out string key. See the file [p2r.conf(p2r.conf) for an example setup.

Format of the Output TFile/TTree

The format of the output file, including Tree and Branch naming are describing in the accompanying document
