Autosomal DNA Segment Analyzer (ADSA) - Version 2

With more people testing all the time, you now have more matches! Which is good. However, ADSA now has more matches to deal with which makes for longer reports and the possibility that your browser will become overloaded. So the default for the ADSA minimum segment size has been increased from 7 cM to 10 cM. You can still change it manually to any value you wish, however. But first-timers who take all the defaults should be more successful in getting their ADSA reports to complete successfully.

ADSA only works with GEDMATCH and the Family Finder test from Family Tree DNA.

The Autosomal DNA Segment Analyzer constructs tables that include match and segment information as well as a visual graph of overlapping segments, juxtaposed with a customized, color-coded In-Common-With (ICW) matrix that will permit you to triangulate matching segments without having to look in multiple spreadsheets or on different web pages. Additional information, such as ancestral surnames, suggested relationship ranges, and matching segments and ICWs on other chromosomes is provided by hovering over fields on the screen. You may also generate emails to persons you match from the page. The web page produced by this program does not depend on any other files and may be saved as a stand-alone .html or .htm file that will function locally or offline in your browser. You can also email the saved report as an attachment. If you want to quickly see what this does, you can try out a working sample output for a single chromosome, but the default option is for all chromosomes to be displayed.

PLEASE READ THE ADSA MANUAL for step-by-step instructions for using the tool and a section on troubleshooting problems you may encounter. If you just want to get started without a lot of reading, you can follow the steps in the Family Tree DNA Quick Start Guide or the GEDMATCH Quick Start Guide. There are also special instructions for people with Ashkenazi ancestry. If you wish, you may still run the older version of ADSA (Version 1) from files.
