abacusutils 2.0.1

Python code to read halo catalogs and other Abacus N-body data products

abacusutils

abacusutils is a package for reading and manipulating data products from the Abacus N-body project. In particular, these utilities are intended for use with the AbacusSummit suite of simulations. The package focuses on the Python 3 API, but there is also a language-agnostic Unix pipe interface to some of the functionality.

These interfaces are documented here: https://abacusutils.readthedocs.io

Installation

The Python abacusutils package is hosted on PyPI and can be installed by installing "abacusutils":

pip install abacusutils

or

pip install abacusutils[all]

For more information, see https://abacusutils.readthedocs.io/en/latest/installation.html.

Usage

abacusutils has multiple interfaces, summarized here and at https://abacusutils.readthedocs.io/en/latest/usage.html.

Specific examples of how to use abacusutils to work with AbacusSummit data will soon be given at the AbacusSummit website: https://abacussummit.readthedocs.io

Python

The abacusutils PyPI package contains a Python package called abacusnbody. This is the name to import (not abacusutils, which is just the name of the PyPI package). For example, to import the compaso_halo_catalog module, use

import abacusnbody.data.compaso_halo_catalog

Unix Pipes

The pipe_asdf Python script reads columns from ASDF files and pipes them to stdout. For example:

    $ pipe_asdf halo_info_000.asdf -f N -f x_com | ./client
