Library for converting python numpy datastructures to the ROOT output format.
Free software: GPL v2 license
Documentation: https://broot.readthedocs.org.
The ROOT(https://root.cern.ch/) data analysis framework is used much in High Energy Physics (HEP) and has its own output format (.root). ROOT can be easily interfaced with software written in C++. For software tools in Python there exists pyROOT(https://root.cern.ch/drupal/content/pyroot). Unfortunately pyROOT does not work well with python3.4.
broot is a small library that converts data in python numpy ndarrays to ROOT files containing trees with a branch for each array.
The goal of this library is to provide a generic way of writing python numpy datastructures to ROOT files. The library should be portable and supports both python2, python3, ROOT v5 and ROOT v6 (requiring no modifications on the ROOT part, just the default installation). Installation of the library should only require a user to compile to library once or install it as a python package.
Secondly the library can be used to convert other file formats that store information in numpy-like structures, such as HDF5, to ROOT.
Installation
To use broot a user must have installed python, ROOT and be able to compile C++ code. To install:
pip install broot
To use the examples clone the repository and run:
python setup.py develop
Use
To use broot one needs libRootOutput.so and RootWrap.py
RootWrap can be imported in any python file and a new RootOutput instance can be made:
from broot import RootWrap
OUT = RootWrap.RootOutput()
Two example scripts are provided in ‘examples’.
‘convert.py’ demonstrates the functions available using some ndarrays.
‘hdf_to_root.py’ is a first implementation of a HDF5 to ROOT converter (HDF5 file not provided).
Current support:
python2
python3.4
ROOT v5
ROOT v6
compiles on gcc versions with c++11
compiles on gcc versions without c++11 (see branch no-c++11)
tested on GNU/Linux
Todo list:
Proper Makefile instead of ‘compile.sh’
Python package
HDF5 converter class
OS support for Windows and Mac
