ytree is a tool for working with merger tree data from multiple sources.
ytree is an extension of the yt analysis toolkit
and provides a similar interface for merger tree data that includes universal
field names, derived fields, and symbolic units. ytree is able to load in
merger tree from the following formats:
- :ref:`load-ahf`
- :ref:`load-ctrees`
- :ref:`load-ctrees-hdf5`
- :ref:`load-lhalotree`
- :ref:`load-lhalotree-hdf5`
- :ref:`load-rockstar`
- :ref:`load-treefarm`
See :ref:`loading` for instructions specific to each format. All formats can be :ref:`resaved with a universal format <saving-trees>` that can be :ref:`reloaded with ytree <load-ytree>`. Individual trees for single halos can also be saved.
If you have halo catalog data that can be loaded by
yt, then you can use the
treefarm package to create
merger trees. treefarm was
once a part of ytree, but is now its own thing.
