I so appreciate that RootsTech does the "Live Streaming" I have watched passed years and haven't been able to attend the Event. I am hopeful of attending at some point in my life, fingers crossed. I am still debating about the Virtual Pass..
Thank you for bringing this feature to my attention. I especially appreciate your comments related to endogenous ancestors - which is a perspective that I must continually deal with (100% endogenous) I'm curious to see how it reacts to my matches.
Going to the 1to1 really matters -- I set my lower cM to 20, and the kit at the top of the largest cluster (By Cluster Size) shows 40.7 cM with me, but clicking on the 40.7 cM reveals "No shared DNA segments found". Dropping the 1to1 threshold from 7 cM to 3 cM reveals a lot of small shared DNA. I would like to have parameters not just for total cM but also for largest segment cM.
Myheritage now offers a similar tool. I was wondering, how is it grouping people in a cluster. What is the determining factor. To be in a cluster do you have to match with more then "x" amount of other people in the cluster etc?
Hey, thanks for the video. I have 16 clusters on myheritage. The min threshold is 15 cM. My friend has 33 of them with min threshold 20 cM. So myheritage knows the best threshold for a user and each report varies? Does it also mean these 16 clusters I have are my ggg-grandparents? I know there are 32 in total, but I know there is always room for more clusters. Any idea?
I'm trying to obtain a cluster diagram that has a particular GEDmatch kit in it. The kit is a 10.8 cM match to the cluster kit person. I've tried several thresholds but fail to find the 10.8 cM in the clusters. What is the trick for forcing a particular match into the cluster? Thank you.
Is there any way to use the clustering tool when you belong to one of the Gedmatch forums? I'd like to run it against my matches within a specific group.
I tried clustering for the first time and the search came back with not enough kits to perform a cluster. How do I overcome this issue. I played the upper and lower thresholds but still got nothing.
I would try and copy the whole page and paste it in Excel. If that doesn't work, you would have to get into the coding of the HTML with a third party program.
the gedmatch auto cluster tool no longer lets you enter a lower and upper threshold the largest lower # is 35 this doesn't work well for me due to endogamy can you please offer any suggestions? - thanks
Endogamy is a pain (as you already know). I don't have it in my family and I haven't worked with any clients that have it so I am very unfamiliar with how to deal with it. I would suggest looking up Leah Larkin. She has some info on her website about endogamy. thednageek.com/blog/
Andy, it looks to me that clustering will have the effect of losing matches that stood out previously because of the amount of match. For instance, my wife’s top match in the one to many was a relative that shared 130 cMs, and the second on her list was an 85. Then it dropped down t0 the 50s and 60s and kept dropping slowly (until I lost interest) LOL. So the clustering might miss a lot of potential due to the thresholds. Can you address that?
Clustering doesn't consult close matches. It clusters your more distant matches. It's a tool that can help you visualize how they are related. So, start by identifying your close matches. Then leverage your more distant ones. It's just a tool in the tool box.
I am Ashkenazi and when I used the defaults I got one huge cluster with 483 matches. Following your suggestion I change the thresholds to 20 and 30 which produced something more reasonable but which had some strange things as well. The first four cluster ranged from 2 per side to 4. The next 9 x 9 but it included both green and purple (lavender?) boxes. There were other clusters with mixed colors as well and colored boxes that seemed to be floating off on there own but might have really been another mixed color cluster I suppose. Then I got a huge cluster as you predicted. I thought that would be the last one but scanning further I got another bunch of small clusters after it. Some of these were also mixed colors. What can you make of this and what do you suggest I try next?
Hello, I have been watching your videos, trying to find the biological parents of my great grandmother. I'm only missing two of my 16 second great grandparents. I'm still having a hard time determining who they are.
Hello can you please explain how to save clusters when there is no right click option to save on my version of Gedmatch please (I am in Australia) thanks
The "save as..." function may not work with a Chrome browser. Try to use "Save as type" of "Webpage, Complete".......or use a different browser like Microsoft Edge to "save as." Then your saved HTML file will open in either browser in the future.
i tried to save the graph your way, but all i saved iar the directions ! i see nothing else on the html (full screen), no arrows to move around..... what am i missing ?

I'm not exactly sure I fully understand what Cluster by average cm to Reference kit means. How doe sit differ from order by kit cms with the reference kit? I see they produce very different results, but I'm not sure I understand the reason.
The average looks at all the kits in a cluster and averages the amount of cM. Then it orders clusters by this average number. Order by kit cM looks at the cluster that has the highest individual kit cM, the next cluster will be the next highest, etc. So if you had a bunch of matches with 30cM and 1 with 200 cM, then that cluster would be at the top.
From what I understand the government and local authorities have access to gedmatch. People are literally giving up their freedom, and others without their permission. Interesting, the new ways of the world.
Please watch this video to better understand how much government and law enforcement gather from your DNA, if anything. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-T9Edt6Vew-c.html
