There is a wonderful site at http://www.y-str.org with many good tools for Y DNA and autosomal DNA that run as programs on your PC plus a cool ISOGG Y tree add-on for the Chrome browser. My specific interest at the moment is figuring out which Y SNPs are already tested by 23andme so as not to test them again at FamilyTreeDNA since my Dad has kits at both places. I blogged about how to do that manually back in February, but now there is a program that will do that for you. However it took me a while to figure out how to do what I wanted from the instructions given, so I will do a step-by-step tutorial in this post in order to remember what I did.
First download your raw data from 23andme by going to the “Browse Raw Data” Page which is listed in the menu that appears under your name on the top right. Then on the raw data page click on “Download” in the second top bar on the right hand side. This takes you to a page with various warnings and requires that you reenter your password as well as the answer to your secret question before it starts the download.
Save the download file somewhere that makes sense for you. I have a folder called RawData in the folder DNA that I use. Once the raw data file is downloaded, you will need to unzip it before using it with the various tools. To unzip in windows all you need to do is open a file explorer window (a manila envelope is the icon) and then right click on the file name to get a little menu that includes “extract all” which is the one to click.
Now go to http://www.y-str.org/2014/04/23andme-to-ysnps.html and download the program which turns the Y SNPs from your 23andme raw data file into the names in ISOGG format.
When you run this program on your PC you get a little window. Click on “File” in the upper left and then the menu item “Open 23andme raw-data.” Use the file box that comes up to find the unzipped text file from your raw data download. Then it will translate the data into ISOGG named SNPs as in the image on the left. Now click on “File” again and then “Save Y-SNPS.”
Now you have a text file of the SNPs which you can use with the chrome add-on to see where you fall in the current ISOGG tree. This new file can be opened with notepad or wordpad. Click on it in the file explorer in order to open it and have the data handy for the next step.
To get the chrome add-on go to this page http://www.y-str.org/2014/04/isogg-y-tree-addon-for-google-chrome.html and click on the words in red “Install: ISOGG AddOn Chrome AddOn” (or click it here).
Once you have installed the ISOGG add-on, you need to put the Y SNP data you created above into the options for the add on. To do that you need to click on the three red lines at the far top right of your chrome browser and then in the resulting menu click “Tools” and then “Extensions.” This will show a list of your extensions, the ISOGG one looks like this:
Click on the blue “Options” to get to the page where you input the Y SNP data. You can input the data from up to 10 kits there. Using the edit menu in your notepad that has the Y SNP data open you can select all and then copy all in order to paste it into the box for your kit on the options page for your add-on.
Once you have the Y SNP data loaded, you can go to your section of the ISOGG Y tree to see your tested SNPs highlighted. The URL is http://www.isogg.org/tree/ then click on the letter for your haplogroup, for us it is R. On the page for your haplogroup you will see lots of new stuff. First there is a select kit dropdown box on the top left. Then every SNP that has been tested by 23andme is shown in green if it is positive and orange if it is negative. Note the options button, this is a quicker way to get to the options page for the ISOGG add-on.
In our case the SNPs indicate R1b1a2a1a
Next to look at my brother…
Thanks to user Axel on 23andme, who pointed out a thread about these tools in the community there.
