529andYou version 3.3.0.0 collects matching segment information about DNA matches and stores it in a local SQLite database on your computer. If you click on one of your DNA relatives to bring up his or her comparison page, you will see a button labeled "Triangulate into 529andYou" immediately below the list of relatives in common. Clicking on this button will compare you and your match to everyone on that list who has "Yes" in the "Shared DNA" column and store it in the local database. Clicking on the "Open 529andYou" button will generate a page where you can review these and other comparisons.

Alternatively, you can go to your DNA comparison page and select relatives to compare to one another. Clicking on the "Compare into 529andYou" button will cause the designated comparisons to be silently performed into the 529andYou local database in the background. Once again, clicking on the "Open 529andYou" button will generate a page for reviewing these and other comparisons.

Note that matching segments are rounded to the nearest millionth base pair for backwards compatibility with records downloaded at a time when 23andMe similarly rounded all segments.

A variety of controls and functions are accessible from the 529andYou page. Some less obvious functions include:

"Download CSV": downloads a CSV file that can be loaded into spreadsheet programs like Excel; holding down the shift key while clicking will include 23andMe ID's in the downloaded CSV file. If 23andMe ID's are included, the file can be re-imported using the "Import CSV" button. Alt-clicking will also include "chromosome 100" matches that 529andYou uses internally to track whether two people have been compared to one another.

"Download GEFX": downloads a file that can be imported into Gephi (https://gephi.org/)

Phase: This field is intended to show the parent through whom the first listed person is related to the second listed person. The options and some examples for setting your own phase (assuming that your own name appears first) are:

? (unknown) anyone you don't have enough information to classify further

User reviews

Doesn't seem to work any more. First error is : Failed to parse Relatives in Common table, and then 23andme drives on to onto Captcha and nothing can be done. This issue has been reported before on other sites but no response has appeared. Sad that another great idea is being provented from operation.

It's 2019, now, and 529andYou works great! The 529andYou matches reports are very helpful, even without getting into the GEXF data plots. The Delete All 529andYou Data button is a bit large: don't click on it by accident! Back up your data. There is a learning curve for GEXF. I watched lots of YouTube videos to learn how to use it. GEXF is a generalist tool; you will have to experiment to get the useful results you want (for example, I remove myself, my mother, my sister, and my son from the database before plotting clusters of relationships). I'm trying now to learn how to manipulate the data in the database to get even more meaningful plots of data (I want to pull out how my mother and father are related). I wish there were a way to download data for all of my matches at once: I have 1056 matches, and my mother has 1062. It's going to take at least a day of paging through every match's page to acquire all that data. I've enjoyed this extension a great deal, and learned a lot, not just about my genealogy, but about how these graphs work.
