There is an interesting option in Admixture Studio that lets you analyze your RAWs by segments.

This feature is useful when comparing the ancestry composition given, for example, by 23andme.

How to use it

Create a template as follows:

Chromosome,Start Point,End Point

Copy it to the clipboard and paste it using the Paste button of the Segment to Analyze panel.

23andme Ancestry Composition CSV file

You can paste the content of your Ancestry Composition CSV. Choose the ancestry you want to check. Then run the calculator.
