This script is intended to be used to generate halo catalog and merger from python.

It is using AdaptaHop (also named HaloFinder, because why not) from Aubert, Pichon & Colombi 2004 to build the halo catalog as well as HaloMaker (?).

The source of HaloFinder can be found at https://gitlab.com/cphyc/HaloFinder on request. The source of TreeMaker can be found at https://gitlab.com/cphyc/TreeMaker on request.

First you need to get the sources

$ git clone https://github.com/cphyc/yt_halofinder.git

You then have to customize the CONFIG variable in yt_halofinder/control.py to match your installation. The paths should be absolute to your own HaloFinder and TreeMaker. The BR is for the BIG_RUN option of these two softwares, see their doc for information about it.

Once you're done, fire up a terminal, go within the yt_halofinder root directory and execute

pip install .

That's it! To get an example, see the Example section.

For a complete example, see the Example.ipynb file.
