I combined the files into Ancestry.com format and removed duplicate positions by chromosome number, keeping the Ancestry values which appear to always be the same except sometimes reversed between the two companies. For example, AT might be TA on the other.
I uploaded the megafile to GEDmatch.
Eurogenes K13 test uses the following number of SNPs for the kits:
Ancestry 172,090
LivingDNA 58,368
Combined 174,761
Therefore the Eurogenes calculator only looks at 2,671 SNPs in the LDNA file that aren't already included in the Ancestry.com file.
Most of the critical locations from the LDNA file are being examined based on the good approximations of ethnicity. That could mean that many of the Ancestry.com (which is almost the exact chip as 23andMe these days) values aren't useful to the Eurogenes calc.
There is a lot of SNP data in the LDNA file that could be utilized in some way. How can we tap this potential?
My new file has 1,127,303 SNPs, which doesn't count the YDNA from either.
There is very little overlap between the two.
