I'm vaguely aware that Ashkenazis seem to plot somewhere in the vicinity of some Southern Europeans but common sense says Israel lies east of Italy and K13 is North/South calculator so to add East/West dimensions it would seem to me you would use K15 even though K13 seems more 'popular' that is not argument for it legitimately.
Suggestions that are not set in stone but seem worth trying to me :
The original K15 seems lackluster due to mostly limited samples sets or whatnot so you can try K15 on :
1.)genoplot.com
2.)AdmixtureStudio (only runs on Windows and perhaps macs)
3.) K15 Vahaduo updated I think there is an option now to reduce it to four populations but if you want a more even break you can use the source data in R or RStudio or whatnot.
I will quickly demonstrate what I mean, to a limited extant, real quick. I consider myself British ethnically but since K13 is straight North/South it gives me some 'Irish' and 'Welsh' crap. BTW, I don't take any of these 4 way things as gospel I pay more attention to the single 1 population and almost ignore everything else :
K15 from genoplot :
1.)England + England + Norway + South Dutch
********************
1)England 2.91
2.) Dutch 3.13
3.)Scotland
From K13 genoplot :
1.)Welsh + Welsh + Scottish + North German 2.70
2.)Welsh + Welsh + Irish + North German 2.77
1 .)English 3.91
2.)Irish 3.98
3.)Welsh 4.13
^ sorry , but there is no way I'm 50% Welsh which goes to show this is a north/south calculator like I said. I can entertain the idea of being 25% Irish or 25% Welsh but 75% Welsh and Irish or Scottish is too much man IMHO.
Also, if you notice the single population breakdown for K15 seems more logical, at least for me, too. I dunno, all I know is what works best for me so your mileage may vary. Like I said all I can do is make suggestions but I can't proffer them with 'authority'. However, it seems to me you might be using the wrong tool for the job.
What about Jtest ? Did you try that ? That would perhaps the best tool for it in the end I think it is based on EUtest and K15 is basically EUtest version 2.
