Y-haplogroup from atDNA raw data

In the autosomal DNA tests of 23andme and Living DNA, the Y-haplogroup and the mt-haplogroup are displayed directly. Many don’t know that the raw data, of all male atDNA testers contain information (Y-SNPs) for the Y-haplogroup and can be extracted with tools like the Morley Predictor. (Only FTDNA removes these Y-SNPs from the raw data).
Irrespective of which company the atDNA test was done with, it makes sense to have a closer look at the results, because there is much more information in it than some people think. If you get an “old” haplogroup displayed, even though younger branches are tested, it can mean that you are sitting on a rare branch.
