'weac' calculator

This new calculator places individuals on the West Eurasian cline. This cline is the first-order description of variation in West Eurasians, with populations from northern and western Europe falling on one end, and those from the Near East on the other.

On the left, you can see the populations on which the calculator is based, sorted on their average "Atlantic-Baltic" component. The raw data can be found in the spreadsheet.

Note that the main purpose of the calculator is to place European and Near Eastern samples on the West Eurasian cline, and to do so, some African and East Eurasian populations are used as controls. Other types of ancestry (e.g., South Asian or Amerindian) may register as Far-Asian in the context of this test.

You can download the calculator RAR from here (Google docs), or here (sendspace).

You need to extract the contents of the RAR file to the working directory of DIYDodecad. You use it by following exactly the instructions of the DIYDodecad README, but always type 'weac' instead of 'dv3' in these instructions.

Terms of use: 'weac', including all files in the downloaded RAR file is free for non-commercial personal use. Commercial uses are forbidden. Contact me for non-personal uses of the calculator.


  1. Thanks for your work on the DIYDodecad calculators! In my estimation, you've greatly increased my ROI in testing with 23andMe.

    Best regards,

  2. Could you please post the results of a few south Asian populations using the weac calculator? I am just curious how they will turn out.

    Thank you.

  3. Could you add also HGDP Basque results? Thanks,

  4. Can you map the Dodecad 12 onto the weac 4 with a coefficient matrix? My rough use of two whole data points indicate that 55% of one's Mediterranean gets put into Atlanto-Baltic, with the remainder going to Near East, while 8% of West Asian goes to Atlanto-Baltic and the remainder to Near East.

    The other components should map pretty singly, I think (well, except for East African. That probably maps to 1/3 to African 2/3 to Near East.)
