Ancestral Family Tree DNA Testing / Re: New website: auto-clustering your matches

I try to keep groups of shared matches in a spreadsheet. Obviously, the clustering, visualisation, and time-saving offered by Genetic Affairs would be a bonus.

The drawback with Ancestry is that Shared Matches only show people with above 20 cMs (“4th cousins” or closer). If you look at someone with, say, 10 cMs it only shows those with 20 cMs or more. You cannot see shared matches between  “Distant cousins”.

Does anyone know if this new tool picks up the shared matches between these, say, 10-19 cMs or distant cousins?

Distant cousins also have shared matches, but in that case the share at least 20 cM while they could share less with you.

Hi there,

I found this thread and thought it might be a good idea to come over and try to explain some more. First, I am not accessing any hidden data source on Ancestry, I wish they would provide the chromosome data but I still haven't found it :-). In addition, I am not sure if you have the Leeds methodology (https://www.danaleeds.com/) but my method is more or less a Leeds on steroids. The added value is in the automated clustering of the matches and the visualization also helps in the analyis. I could try to come up with reasons to use it but luckily yesterday a similar question was raised on FB, the replies are excellent so if anyone wants to read about how people employ the AutoCluster approach: https://www.facebook.com/groups/geneticgenealogytipsandtechniques/permalink/549573322173039/

Now for the aspects of privacy. I understand that it might difficult for quite some people to hand out the login credentials of these sites. Personally, I would probably feel the same. I wish I could use the old API system of 23andme. Using that approach, I could just ask a user for permission to only see his relatives. For Ancestry, it is possible to create a dummy account which is then given limited rights. I think it is impossible to download the raw results without performing some manual invocations on the concerned websites. The DNAGedcom tool that is already around for quite some years is using a similar approach with respect to downloading matches but ofcourse they don't store the passwords on their server, everything is local. I address several of the aspects of security on my site, so feel free to look around.

Feel free to ask for more info, I don't have a lot of time but I do think it's important to explain as much as possible.
