Welcome to ytree.

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 can create merger-trees from Gadget FoF/Subfind catalogs, either for all halos or for a specific set of halos. ytree is able to load in merger-tree from the following formats:

All formats can be saved with a universal format that can be reloaded with ytree. Individual trees for single halos can also be saved.
