spmcdonald: GEDmatch does not have a tool for that. If you have 3 or more uncles or aunts who are all siblings, then you should use Visual Phasing to identify all their grandparents: https://thegeneticgenealogist.com/2016/11/21/visual-phasing-an-example-part-1-of-5/ If you have the raw data of any close ...

Bizlovr: These files are not easy to work with. I'm trying to directly analyze them myself (I have some skills with this sort of analysis) since I don't like the black box analysis tools that the genomic genealogists use. Getting down and dirty and playing with the ants is easier for me than just getting ...

Ian: If you’ve already done Ancestry, then I’d recommend 23andMe as the other one which will give you the greatest number of different SNPs to use. Only 13% of Ancestry and 23andMe’s SNPs were in common and you should end up with about 1.1 million SNPs by combining just those two tests. Also you’ll get ...

Kendraz: When I purchased my kit back in August 2018, the hard drive with the BAM and FASTQ files was included free of charge. I did note in November that they started charging $69 extra for the hard drive containing your raw data. I am purely looking at the short versus long reads for the purpose of ...

Ah, yes. Evert-Jan: Take a look at Shelley's article.

Sullrich: Yes, that’s an excellent example of how the shared SNPs are very dependent on the chip that is used. Thanks for the offer of SNPs. I’d love to see a sample of Living DNA’s raw data from their new chip.

Interesting. You got over 100,000 more usable SNPs from your combined file than I did. That's a lot. I wonder why. And thanks for your link to Krahn's program. I'm a Windows guy, but his template will be of interest to me. I'll likely be custom programming my own extract once I get my BAM file. Yes, Dante ...

Interesting, Jim. Of course, when someone has mapped as much of their chromosomes as you have, you're a step up on most of us and can leverage that data with other tools. So it is good to know that you found clustering useful on top of everything else you've done.

Thank you Jonathan for your comment, and for creating your Shared Clustering tool. See my next blog post Comparing Genetic Clusters that compares the specific results. I use the 8 people who I know "on paper" how I'm related to, to evaluate the assignment similarities and differences between yours and the ...

I do recall, Leah, last summer I tried RootsFinder's their very innovative 3D visualization of triangulations. They even the ability to associate the triangulation "blobs" (if I may call them that) with an ancestor and color them. But that functionality is not possible for AncestryDNA where you do not have ...
