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.
=====Ancestry=====
Ancestry.com [https://support.ancestry.com/s/article/Chromosome-Browser?language=en_US does not have a chromosome browser ] and its data thus lacks some of the information that other vendors provide. An alternative format is therefore used for Ancestry DNA matches. This takes You can find this information by going to your DNA Matches comparison page and selecting the link to show the [https://support.ancestry.com/s/article/Understanding-Unweighted-Shared-DNA?language=en_US popup-page] that list the form of a note with a single line specifying '''Shared DNA''', '''Unweighted shared DNA''' and the '''Longest segment''', in that order, separated by tabs result: [[File:Ancestry.com-unweighted-dna-example2025.png|thumb|450px|right|An example of a DNA match where the individuals share 55cM or commas, like soidentical DNA from a recent common ancestor.

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.
