You can install the {{man label|DNA Segment Map Gramplet}} on the bottombar of one of the People or Relationship category list views.
Each person with shared segments will be a separate Association. The Notes in the Association should contain the shared segment info as calculated by the vendor.
From this information you can create a note with a single line specifying '''Shared DNA''', '''Unweighted shared DNA''' and the '''Longest segment''', in that order, separated by tabs or commas, for example screenshot the result would be: <code>55,72,21</code>

====Configuration====
The following are capabilities that are currently disabled but can be enabled if user desire. These add complications to the user interface and are deemed not beneficial
The <code>[map]</code> section of the gramplets config file <code>DNASegmentMap.ini</code> has the following options. Remove the comment (double semi-colon) and edit as needed while Gramps is not started. Changes are not reflected until the next time the Gramps is started.
==== Example ====
[[File:DNA-SegmentMapGramplet-addon-Associations-Note-with-DNA-data-example-60.png|thumb|600px|right]]
Create an Association of type DNA as described in the [[Gramps_{{man version}}_Wiki_Manual_-_Entering_and_editing_data:_detailed_-_part_1#Associations|Association]] page to Person A. Add a Note with the DNA shared segment data. Set the Note private if you do not want the data printed in reports. (For this example use the [[#DNA_Example_data|DNA Example data]] above.)

=== Reference Info ===
==== Centromere Areas ====
Machines have difficulties to read the area around the centromere. There are less SNPs to read, therefore there is higher probability of false positive matches. For example, if you have a match exactly around the centromere, then it is most probably a false positive match. The area of the centromere id dependent on the Build (36, 37, or 38). For example, the list for Build 37 (the most common) is

== Issues ==
* When the user has no DNA data, have the gramplet still show a blank chromosome chart & legend with a message link to this page?
* Legend with rollover tooltip does not work (win 10)
=== Future feature To Do ===
* Add user config to specify the Association Type. Currently, the Association Type of DNA is used for this gramplet. It could be made user-controllable.

That is, where Person John Smith has a DNA Association (with an Association Note) to Person Jane Jones, then if Jane Jones does not have a corresponding DNA Association to John Smith, it will be created which shares the Note.
