Dear Barton, You are correct that it isn't practical to get all of your matches to upload their data files to GEDmatch, but you can certainly try to do that if you want to. The difference between GEDmatch and Family Finder is that you can compare any two of your matches in GEDmatch to see if they match each other on the same segment that they match you on. You can't do that in Family Finder. In GEDmatch you first run the "One-to-many" comparison and make note of the GEDmatch numbers for your matches on any particular segment. Then run the "One-to-one" comparison to compare your matches to each other.

But you would have to have all ten of those kits uploaded to gedmatch, which isn't very practical. But even if you could do that, how is gedmatch different from using the chromosome browser in FTDNA, where you can download all your segment data and see who is matching you where, but not know which side of the chromosome pair (unless you can triangulate or easily determine using ICW)? Thanks, Barton
