Tracks 23andMe Matches using a local database

Image from store 529andYou
Description from store 529andYou version 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 M (maternal) your mother or anyone to whom you are related through her but not through your father P (paternal) your father or anyone to whom you are related through him but not through your mother B (both) your descendants, your full siblings and their descendants, any double cousins to whom you are related through both parents N (neither) false matches (usually less than 7 cM) who cannot be reconciled as coming from either parent While you may ultimately conclude that a particular segment shared with someone to whom you are known to be related through both of your parents derives entirely from only one of your parents, it is recommended that you start with the B label for such people if your parents haven't been tested, even if Family Inheritance shows only a single strand match on the segment. Label: Any set of labels you choose Match phase: This field is intended to show the parent through whom the second listed person is related to the first listed person. Please see the Phase field above for details. Match label: This field allows you to enter a label that indicates something useful about how the second iisted person relates to the first listed person. Please see the Label field above for details. Common ancestors: This field allows you to enter information about the most recent common ancestors for the two people who match. This field cannot include commas. By default, these phase, label and common ancestor fields are not displayed when the display mode is anything other than "Edit Phasing Information and Ancestors". This maintains backwards compatibility and minimizes clutter for those choosing not to use these new fields. To override this default, you the radio buttons on the line that starts with "Always display:" to select the category or categories of new fields that you want displayed (these will take effect the next time you display new information). ll components of 529ndYou version except the associated PNG image files and the javascript file FileSaver.js are hereby placed into the public domain.

  • (2019-01-22) Paul Jackson: 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.
  • (2018-09-14) Cindy Barnett: Very helpful
  • (2017-12-06) mehedi hasan: very nice
  • (2017-08-11) Laurence Smiser: As long as 23andMe doesn't change their page formatting it work great. In combination with Gephi 0.9 you can see all or at least most of the interconnections among your matches. You are presented with an initial mess but using the Layout window you can reposition the matches to give you a visual view of these connections making more sense of the interrelationships.
  • (2017-04-30) Efrain Sanchez: ok
  • (2016-05-18) Donovan Smith: Until I was switched to the new 23andme website. Now I can't even access the 529andYou database the extension generates.
  • (2015-12-16) Dale Wallace: I was loving this extension as the data it collected could be imported into GenomeMate, and then 23&me came out with their new and not yet improved website. It you are planning to adapt to the new site, I have experience testing and recreating scenarios that produce the unexpected results. I'm willing to help if desired.
  • (2015-07-30) Kuba Krchak: So simple yet powerful! Especially if you want to generate comparison for all of your shared matches with a new kit in your profile, this is godsend.
  • (2015-01-11) Lisa Landrum: Very helpful in adding info from 23andme to GenomeMate!
  • (2014-09-10) Marlaine Hysell: Very helpful extension. Thank you.
  • (2014-06-11) Rhonda Lucas: This is the BEST extension to use with 23andme to compare 'in common with' matches. It's a time saviour. My wish? There was a way to edit the actual database entries to remove or merge people that change their name since you first checked. I have multiples of people eg J. Smith > James Smith and back to J Smith, all the same person.
  • (2014-05-23) Shane Spitzer: Good extension when combined with Genome Mate. Any way you can allow us to sort by genetic distance rather than chromosome? Also, it would be wonderful if there was a more automatic way to have it run overlapping segments. Clicking one by one is highly time consuming.
  • (2014-05-19) H Johnson: Re Fran Mason's comment, the icon appears after you click "view in table" as indicated in the screenshot with the red "1" and arrow. Hope this helps. Just started using, so will see, but looks good so far!
  • (2014-03-16) Angel Piper: If you use 23andMe for serious research, you absolutely need this extension. If you are adopted and searching for family or just trying to figure out where your DNA matches fit into your pre-existing family tree, then this extension will save you countless hours. As a bonus, because it logs the information about the match that each user has with you into a database and stores it on your computer, you never lose the information about that match, even if that match stops sharing with you.
  • (2014-03-14) Fran Mason: Icon that's supposed to appear in the menu bar in Chrome is not there even though the extension is added to Chrome and enabled. So I can't use the tool at all.
  • (2013-07-16) william mccombs: This is a real handy feature and helps tremendously from being limited to the few 23&me download comparisons. If you cut and paste into Excel you can really make comparisons of all your matches.
  • (2013-07-02) Brian Pardy: This is extremely helpful for anybody trying to do genetic genealogy using 23andMe. I have been manually logging the data this extension stores automatically and it has already saved me a lot of time and helped me make connections I may not have found otherwise.
  • (2013-06-28) Tracy Drane: Kind of cool!
  • (2013-02-19) Andrew Rivlin: Seems like a handy device/app.
  • (2012-12-28) Sam Allardyce: wowowowowowowow

    429 error
  • (2020-05-12, v: Bonnie Krieger: Extension fails.
    I get this error message:Failed to parse Relatives in Common table
  • (2020-02-08, v: Dealraider Sales: Extension is no longer working on 23andMe
    It ends up hiding the shared relatives (or prevents it loading) and then using the compare with or triangulate does not work either.
  • (2020-01-25, v: Kuba Krchak: [compare] not working
    It seems the problem is that 23andMe no longer has Access-Control-Allow-Credentials: true That is why oreq.withCredentials = true does not help / work. I am not a JS guru, so it can be more complex... Anyway, the https://you.23andme.com/tools/ibd/?human_id_1=1&human_id_2=2 still works in browser... This is the error: Access to XMLHttpRequest at 'https://auth.23andme.com/authorize/?redirect_uri=https%3A%2F%2Fyou.23andme.com%2Fauth_callback%2F&response_type=code&client_id=you&scope=openid&state=%7B%22origin_uri%22%3A+%22%2Ftools%2Fibd%2F%3Fhuman_id_1%3Dd2f74998d724b34f%26human_id_2%3De4806f4106a61610%22%7D' (redirected from 'https://you.23andme.com/tools/ibd/?human_id_1=d2f74998d724b34f&human_id_2=e4806f4106a61610') from origin 'chrome-extension://nekcpognkifhchlmgddjajmaiplidfhn' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

  • (2020-01-25, v: Kuba Krchak: The [compare] button is no longer operational.
    Thanks for the best genealogical extension of all time once again. Unfortunately, the [compare] button is no longer working for some time, always complains that I am not logged in, even though I am. Persists through different computers....
  • (2019-12-01, v: Rita Carpenter: won't take csv file
    I am trying to import a csv file containing DNA comparisons from 23andme and it keeps telling me that it does not recognize the file format.
  • (2019-09-07, v: Michael Toogood: Location of database
    Where is the 529andYou database? What's its filename?
  • (2019-05-09, v: Laurence Smiser: "Weight" column
    How is the "Weight" computed for each match?
  • (2019-04-17, v: Cornel Strutu: alt+click to download CSV doesn't work in chromebook
    This is the issue: https://support.google.com/chromebook/forum/AAAAmKCdEuss6dDS-PNXI4/?hl=en&gpf=%23!topic%2Fchromebook-central%2Fs6dDS-PNXI4 I think is more likely you'll find a solution than google finding one. Thanks
  • (2019-04-11, v: Laurence Smiser: understanding the overlapping DNA graph
    I want to understand the meaning of the overlap matching graph. I see the principal match in bright red with the other principle in blue. What is the meaning of the lighter shades of red and blue which may or may not be paired with each other?
  • (2019-01-22, v: Sharon Dankwardt: no 529 button
    23&me has changed the page format and now I don't see the 529 buttons anymore :(
  • (2018-10-20, v: Triangulation is not working
    Whenever I click on Triangulate into 529and you on a match page, I get the error "you.23andme.com says Unable to find your name on page"
  • (2018-09-01, v: Laurence Smiser: Gephi does not open lownloaded files
    Severa weeks ago the downloaded .gexf files with "All" selected result in Gehi opening but without the data...It does open when only the subject name is selected. This used to work flawlessly. Trying to open the gexf for All matches file results in the same response. I tried the .csv file with the shift key and all the data is there but the import app doesn't seem to recognize the file data correctly. Could this be related with any policy change at 23andMe?
  • (2018-08-22, v: Laurence Smiser: gephi downloads
    Gephi has stopped recognizing the files I am downloading. The app opens but no data is loaded.
  • (2018-08-19, v: Kuba Krchak: What can we put into the optional match filter?
    Roger, I like the match colors. Can you share some examples of how to get best out of the optional match filter? Can I specify regions on chromosome somehow? Keep up the good work! Kuba
  • (2018-08-17, v: James B: Error Message
