Introduction to FLPTD2Root

At present, the builtin ROOT formatter of flreconstruct only outputs the basic raw and calibrated data banks. To help in user analysis, a simple converter program, flptd2root.py is provided to convert all data banks to a flat ROOT TTree for further analysis.

Installing FLPTD2Root

If you have installed Falaise via Cadfaelbrew, simply do

$ brew update
$ brew install ptd2root

Using FLPTD2Root.py

FLPTD2Root is implemented as a simple command line python program. To get help on the available options, run flptd2root.py with the -h option:

$ flptd2root.py -h
usage: flptd2root.py [-h] -i <infile> -o <outfile>

Convert flreconstruct BRIO format to ROOT

optional arguments:
  -h, --help    show this help message and exit
  -i <infile>   input BRIO file
  -o <outfile>  output ROOT file

To convert a full BRIO format file output by flreconstruct, simply pass the path to this file as the -i argument, and use the -o option to supply the name of the output ROOT format file. For example,

$ flptd2root.py -i example-reco.brio -o example-reco.root

Format of the FLPTD2Root ROOT TTree

The format of the TFile/TTree is fully documented in a README PDF file.
