Sample Data
===========

Sample datasets for generating some small merger-trees are available
for download from the `yt Hub <https://girder.hub.yt/>`__ in the
`ytree data <https://girder.hub.yt/#collection/59835a1ee2a67400016a2cda>`__
collection.  The entire collection (about 358 MB) can be downloaded
via the yt Hub's web interface by clicking on "Actions" drop-down menu on
the far right and selecting "Download collection."  It can also be downloaded
through the girder-client interface:

.. code-block:: bash

   $ pip install girder-client
   $ girder-cli --api-url https://girder.hub.yt/api/v1 download 59835a1ee2a67400016a2cda ytree_data

Within that collection, the ``fof_subfind`` directory contains FoF/Subfind
catalogs generated from a small Gadget simulation.
