LHE to HDF5 File Converter

Introduction

The lhe2hdf5 tool provides a streamlined solution for converting "Les Houches Event" (LHE) files into HDF5 format. The LHE file format is widely used in high-energy physics simulations to store particle event data, including the kinematic information of particles produced in collision events. Both uncompressed (.lhe) and compressed (.lhe.gz) LHE files can be read by the tool. The processed particle data, including particle ID, status, momentum components, energy, mass, transverse momentum, and rapidity, as well as the event weights are saved in an HDF5 file for efficient storage and retrieval.

Getting the Code

To get started you can clone the lhe2hdf5 repository from GitHub using the following command:

git clone https://github.com/dev-geof/lhe2hdf5.git

Installation

To install lhe2hdf5 and its dependencies you can use the following command:

python -m pip install -e . -r requirements.txt

Usage

Script Invocation

lhe2hdf5 -i lhe_dir/ -o output.h5

Parameters

  • i (str): Path to the directory containing LHE files.
  • o (str): Path to the output HDF5 file.
