Pynbody is an analysis framework for N-body and hydrodynamic astrophysical simulations supporting PKDGRAV/Gasoline, Gadget, Gadget4/Arepo, N-Chilada and RAMSES AMR outputs. Python version support adheres roughly to SPEC0.
The documentation is at readthedocs. To get a first sense of what pynbody can do, try the quick-start tutorial or images tutorial.
If python and the standard pip package manager is installed and properly configured, you can simply do:
$ pip install pynbody
If this fails, you may need some more detailed installation instructions.
Help us make pynbody better! As you develop analysis for your science with pynbody, consider making your code available for everyone else to use. You can do this by creating a tutorial or by adding your code to the relevant sub-module and submitting a pull request (make a fork first — see https://help.github.com/articles/using-pull-requests).
When using pynbody, please acknowledge it by citing the Astrophysics Source Code Library entry. Optionally you can also cite the Zenodo DOI for the specific version of pynbody that you are using, which may be found here.
If you have trouble with Pynbody or you have feature requests/suggestions you can submit an issue, and/or send us an email on the Usergroup mailing list.
