The open source tree sequence community
Welcome to tskit.dev, the home of the open source tree sequence community! Tree sequences are a powerful way to represent genetic ancestry and DNA sequence data. The tree sequence data structure, technically a formulation of the ancestral recombination graph (ARG), permits efficient storage and analysis of genomic data, as well as providing new biological insights. This site is a collection of resources to help you learn about tree sequences and associated software, and to help you join the online community of open source developers that makes it all possible.
