0001 Heppy : a python framework for high-energy physics data analysis
0002 ================================================================
0003
0004 This README is for the standalone version of heppy.
0005
0006 Prerequisites
0007 -------------
0008
0009 **python 2.x, x>5**
0010
0011 **ROOT 5, with pyroot support**
0012
0013 Note that you need to ensure that ROOT was compiled with the same
0014 version of python as the one in your PATH.
0015
0016 To check that, do the following:
0017
0018 python
0019 import ROOT

0023 Environment
0024 -----------
0025 Put the heppy package in a directory that is in your PYTHONPATH
0026 For example, you can do:
0027
0028 export PYTHONPATH=$PWD/..:$PYTHONPATH
0029
0030 Check that you can now import heppy:
0031
0032 python
0033 import heppy
0034
0035 From this directory, run the initialization script, which makes a few
0036 executable scripts available to you:
0037
0038 source init.sh
0039

0041 Examples
0042 --------
0043
0044 A simple example are provided in the test/ directory:
0045
0046 cd test/
0047
0048 Create a root file with a tree:
0049
0050 python create_tree.py
0051
0052 Process the root file:
0053
0054 multiloop.py Output simple_example_cfg.py
0055
0056 Investigate the contents of the Output folder and its subdirectories.
