Autoclustering - Large Groups

In my previous post, I talked about the new tool, Autoclusting by Genetic-Affairs. I still believe this is the most powerful tool that's come out to help in analyzing your DNA results in long time. This makes it so much easier to see the in-common matches and figure out how they all might be connected. That first post was after I had generated my initial autoclusters but before I really looked into the results. My initial thought was that I inherited some DNA from an endogomous population that my paternal first cousin did not. Discussing it in various DNA discussion groups on Facebook, the question came up of a potential NPE ("non-paternal event" or "not parent expected"). If this was going to be the case, it would have had to have been an affair that would have come as a shock to many family members so I wanted to be 100% certain before speaking of it to anyone.

Auto-Clustering of DNA Matches

In the Facebook genetic DNA groups, I've seen one subject discussed pretty frequently over the past couple of weeks that I hadn't heard of before. That is auto-clustering of DNA matches. This looks like a spreadsheet of your DNA matches, color coded and clustered into common match groups. The way it works is that for any given colored cluster, each of them should be descended from one common ancestral couple. This seems like a way to better compare in-common matches. Here is how you do it.
