"This work uses voids identified with VIDE\footnote{\url{http:www.cosmicvoids.net}} (Sutter et al. 2014), which implements an enhanced version of ZOBOV (Neyrinck 2008) to construct voids with a watershed algorithm."

Requirements

The package swig needs to be installed and available in the PATH (http://www.swig.org/). It is required by scipy and we have not decided to bundle it with VIDE at the moment.

Quick Start Guide

After installing the package with python3 setup.py install --user, you can execute

python3 -m void_pipeline  your_config_file.py

The VIDE tools are all packaged in the vide package.

Notes for CONDA

If you use a conda installation, you have to be sure to use all the building tools that are consistent. On linux that means for example installing the conda packages gcc_linux-64 and gxx_linux-64. In addition to that it is recommended to define the environment variable LIBRARY_PATH=the_path_of_your_conda_environment_with_/lib. For example if your environment is in '/home/user/conda' you should define

export LIBRARY_PATH=/home/user/conda/lib

You can then initiate the construction with

python3 setup.py build
