Your high distances indicate that you have not run it well, you have to use K13 coordinates.

My distances aren't high. It is 2.314. Your distances are much higher. I have used K13 and it just depends on the Vahaduo you use.

Target: Grace
Distance: 2.3148% / 2.31479278
54.3 Germanic
45.0 Insular_Celtic
0.7 Roman

I've done it again and get Roman this time instead of Balkanic. The first one I used was this one. It just puts the first figure in a percentage and the second figure as decimal. Your figures are 12.471 compared to mine which is 2.314.

Just an example of the differences depending on what you use.

Using Vahaduo with Gedmatch and replacing the source content this is what I get.

Using this vahaduo https://vahaduo.github.io/vahaduo/ this is the result.



So distances are actually closer on the one above.

Lol it's true, I didn't think it could be done from the official Vahaduo. I suppose that the long distances are due to the lack of Iberian references.

Personally it is similar to the result of a G25 model that I got.

I think IBD would be more informative. I would like to see a good study looking at IBD between populations.

Looking forward to having a good look, when get laptop sorted again in next day. Iron age samples in East coast Cumbric speaking now Lothian and the Pictish areas!

First Look at Scottish DNA. Two samples are so close to my parents you could walk there easily from front door. If see more samples will update that. Going to check rest of Britain in comparison with viking data.

[Graham]

Very low sample rate but nice to see some Welsh data. North East Wales looks more like Iron Age mainland Scotland. I'd suspect Cumbria to also look similar. The sample comes from Clwyd, that shares the name of our Clyde.

Might have already been posted, but good to see Wales come out top.

Scotland_IA is very northern by the way

Did you use all the French IA2 samples from the Patterson's paper to make France IA average, only the French IA2 samples from Patterson's study or did you mix them up with the Brunel's IA samples?
Last question; do you think it would make a difference?
