What is DateLife?

DateLife is an open-source web service that allows users to obtain divergence dates for a set of taxa.

How can I use DateLife?

One the DateLife website, [[2]], you'll find the graphical user interface (GUI) for DateLife. From this site, you can enter a list of taxa or a Newick tree and obtain divergence times. Your results can be returned in a variety of formats. There are also several options for how you would like DateLife to conduct the analysis. In the near future, the ability to decorate the tree with fossils will be added.

DateLife can also be queried using scripts. As this resource is fairly new, and the back-end was recently revamped, extensive testing has not been conducted on how heavy use by one user impacts the usability of the resource for other users. Please be judicious in your use, perhaps leaving several seconds between queries or saving your heaviest use for late at night.

How should I use DateLife?

For many projects, creating your own tree with relevant data and calibrations is appropriate (and required for publication). This website uses calibrated trees to calibrate trees. This means that error found in the original chronograms can be magnified throughout the process. While we are confident that DateLife's algorithm for obtaining branch lengths from different chronograms is effective, it is not a substitute for your own analysis in a publication.

Please note that since we rely on open-access data, not all groups of organisms will be present in our databases. If you'd like to submit data you have for the database, please contact us here: [[3]]

How do I cite information found from DateLife?

Citing the original papers for the data is the best way to cite information returned from DateLife searches. Citing the DateLife website is also much appreciated.
