DNA Segment Studio simplifies some of the operation that commonly a genealogist does while analyzing matching segments.

In the current version, this tool has the following features:

  • Segment Inferrer: Analyzes and infers the segments not inherited by someone given a set of matching segments. The idea behind of this tool comes from this two great article from Jonny Perl and Louis Kessler.

How to use Segment Inferrer

I recommend to read the following article to understand how to proceed with segment inferring:

Jonny Perl – Painting your DNA with inferred matches
Louis Kessler – Inferred Segment Matches

To use inferring matches, you need the shared segment result from person A to C and B to C.

For example, person A can be you, person B can be your father, person C can be your father’s second cousin.

The tool is compatible with the following shared segment results:

  • Gedmatch One-To-One results
  • MyHeritage Shared Segments
  • 23andme DNA Comparison table
  • FTDNA Shared Segment

Note: Ensure that the header of the table where is identified what column is each one is copied.

Once you have copied the shared segments from Person B to Person C, use the Paste button that is along to Match 1 label.

Then proceed to paste the shared segments from Person A to Person C, using the Paste button that is along to Match 2 label.

Finally, click on Calculate, this will calculate the inferred segments and they will displayed on the list below and painted in the chromosome browser at the right hand side.
