Iroki tree viewer

Hi! I'm the Iroki tree viewer!


Iroki is a super snazzy online tree viewer (phylogenetic or other kinds too!) with automatic customization using metadata or biom files.

You can visualize your newick trees as well as project count data into colors that you can use to style the tree!


Iroki is research software. If you use Iroki, please cite the Iroki preprint:

Moore RM, Harrison AO, McAllister SM , Marine RL, Chan CS, and Wommack KE. 2017. Iroki: automatic customization for phylogenetic trees. bioRxiv doi:10.1101/106138


To see usage examples and learn about how to customize your trees, check out the documentation.

Getting help
