App to convert Ancestry.com raw data to 23andMe format
On the internet I found other apps that claim to convert Ancestry raw data to
23andMe format, but the ones I found have flaws. Among others, none of them
handled the PAR1 and PAR2 regions of the X and Y chromosomes correctly.
Depending on what SNPs one counts as being in PAR1 and PAR2, most of them
are heterozygotic or homozygotic. In the app I wrote, I used the limits that
23andMe uses to define the heterozygotic or homozygotic ranges.
Here's how to use the app:
1. Down load the Ancestry to 23andMe.zip file.
Heres a link to it:
2. Unpack the Zip file into a folder.
3. Copy your AncestryDNA.txt file into the same folder.
Make sure it is called AncestryDNA.txt.
4. Double click on the Ancestry to 23andMe.exe file to run
the program. The program creates a file named
"23andMe format file.txt" in the same folder.
