I've been using Genetic Affairs to auto cluster for a while now but never really took the time to learn to use it effectively. The tips on clustering with an endogomous population are excellent. I'm going right to the next video. Thank you!
Excellent! His work has grown so much.... Very dense. Thanks for putting this up where I can review! My mother's side is easy to work with. My father's side is a mess of interrelationships. I feel inspired to try again with clustering on his side. I think the targeted clustering might help with that.
Having LDS on both sides and a very full tree for 200 years, I would agree 8 cm is wayy too strict. I know because I can tell because most of my tree is so-well flushed out.
I LOVE LOVE Genetic Affairs, It helped me out a lot. I appreciate this website a lot. too bad about the Cease and Desist letter, but if that match is on Gedmatch or any other site this Genetic Affairs is still very useful with finding common ancestors. Or information that can help with your research.
I was looking into Genetic Affairs and learned Ancestry.com has issued a “Cease and Desist” letter to Genetic Affairs. So it cannot be used on Ancestry.
I have looked at the My Heritage auto cluster feature so some of this sounded familiar. Sometimes you have numerous +7 triangulated matches. On ftDNA you can only look at a max of 7. On My Heritage it is slightly better as you get a scrolling list, but not all of the shared matches are shared triangulated matches. I was hoping there would be a tool that would allow a person to draw from their pool of matches those that are matches on a certain CH. From that subset, then allow for a list of matches that are triangulated with each other. If you were just focusing on a certain CH that might allow for you to see on the same page the super clusters in your traditional CH graphic that appear on the chromosome browser page.
I agree, the AutoSegment tries this approach (if I understand you correctly) but since it cannot distinghuis between maternal/paternal, there will be false positives. The upside though is that by separating overlapping segments into 2 groups (instead of the original single cluster), you just have created 2 clusters. So for some cases, when there are multiple segments not on the same, you'll just have 2 clusters instead of 1.
None of this ever makes sense to me It doesn't help that I have not seen an explanation of centimorgens The only thing I have been able to do is use dna matches where there is a common ancestor or I can find a common person
* If you Google "What is a centiMorgan," you will find 3 RU-vid presentations explaining it, right at the top of your search.. * Also, Wikipedia has information/definitions as well. It showed up on the same first page after my Google search. It is about a part of science you may not have ever seen, so just keep googling, look at the various excellent books available; there is a lot to learn. Here are two books which are recommended. * Diahan Southard has a fairly basic book, "Your DNA Guide - The Book" which will walk you through answering questions you may have. * Blaine Bettinger has his 2nd edition of "The Family Tree Guide to DNA and Genetic Genealogy" available as well. Both these books provide answers to many questions. All the best, give yourself time to learn this complicated stuff. Join a genealogy society. Look for Facebook groups for DNA or Genetic Genealogy.
Clustering is pretty advanced stuff. It makes a lot more sense if you start with a video on the very basics and work your way up. If you are trying to solve a DNA mystery, you will want to make a lot of use of clustering. Otherwise, you may want to skip it until you find a need for it.
Here is my video on What is a cM? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-b3jlZWdOYrk.html Also here is a playlist of all my DNA videos. ru-vid.com/group/PLiMXWjHlj5RQ_iInPLinVtIxjyzn3yE4o
I am confused about the AutoFastCluster files. I use FTDNA and very familiar with Excel. I think understand the 1st file -- column 1= match name, column 2 = cM ("Shared cM" column on FF matches page?), column 3 = notes. But the 2nd file throws me for a loop. Do the "shared matches" in the 2nd column in the 2nd file come from an "In Common With" file? So say my first file lists John, Jane, Jack, Jill. Then in the 2nd file, "John" appears in the 1st column for all the names in his ICW file, which are in the 2nd column, then "Jane" and her ICW matches in the rows after that. Please help! (I'll watch the other videos and probably find the answer, but I've struggled with this for some time and can't seem to get it right!
Thanks! I really enjoyed giving the presentations.
