DNA tools by types of input data

DNA tools use different types of input data:

Raw DNA data tools DNA match results Manual Input

These raw DNA data tools use raw DNA data files. Major DNA testing services like AncestryDNA, 23andMe, and FamilyTreeDNA allow customers to download raw DNA data files. These files contain the “letters” (nucleotides A, C, G, T) that comprise DNA.

These tools use the genetic matches that show up on specific websites like AncestryDNA and Family Tree DNA.

Some tools require a user to manually input genetic data.

Using Raw DNA Data Tools

See list of raw DNA data tools.

Using DNA match results

These tools use the DNA match results for genetic relatives from services such as 23andMe, AncestryDNA or FamilyTreeDNA Family Finder or segment match data.

  • 529andYou A Google Chrome extension for use with data from 23andMe. For details see the reviews by Kitty Cooper and Rebecca Walker
  • AncestryDNA Helper A Google Chrome extension provided by Jeff Snavely which allows you to extract and download a spreadsheet of your matches.
  • DNADNA Free to use software for genetic genealogy visualisation. Currently works with AncestryDNA data
  • Autosomal DNA utility A free tool provided by Wesley Erickson. It allows the user to compare multiple matches at 23andMe or Family Tree DNA in a single chromosome browser.
  • DNAGedcom This site was created by Rob Warthen to help users quickly analyze their data. This site and related tools allows you to download data from FTDNA, Ancestry and 23andMe. In addition, it has the ability to compare many Gedcoms at one time through the GWorks utility. The Autosomal DNA Segment Analysizer provides a visual representation of your Family Finder matches and the overlapping segments. Additional tools are available for a small fee from the DNA Gedcom Client which allows the user to download a list of AncestryDNA matches with centiMorgan data and pedigrees. The information from here can then be uploaded to DNAGedcom and your matches Ancestors are then compared through the GWorks utility.
  • DNA Genealogy Experiment A selection of experimental tools for visualising DNA matches including the Family Finder segment triangulator.
  • DNA Painter A free website created by Jonny Perl which allows the user map DNA segments and identify patterns in the data. For details see the video tutorial from Blaine Bettinger.
  • DNA Painter Shared cMs tool
  • Double Match Triangulator A free program provided by Louis Kessler
  • GEDmatch A free utility to compare autosomal DNA data files from all three testing companies and to compare Gedcom files. A number of other very useful tools are also provided, some for a fee.
  • Genome Mate A tool for comparing autosomal DNA data and identifying common ancestors developed by Becky Walker, a 23andMe member and a programmer.
  • MapsS Europe A tool for advanced genetic genealogists which provides the facility to analyse segment data, calculate genetic distance and convert between builds 36 and 37
  • MatchCompare A free Excel tool for finding in common with and not in common with matches.
  • MedBetterDNA A Chrome extension which enhances the AncestryDNA match system. It puts the notes on the match which is a big timesaver.
  • NodeXL A free Excel template which can be used to visualise AncestryDNA matches. See the detailed tutorial from Shelley Crawford
  • Overlapping segments viewer A tool provided by Staffan Betnér for comparing all matching segments for all matches based on Family Finder data.
  • Pedigree Thief A Chrome extension which "creates an ahnentafel chart from an Ancestry Pedigree Tree" and also "reads a DNA match for csv output." It is designed as an input tool for Genome Mate Pro but can also be used as input for a general genealogy program.
  • Relationship Estimator App A free utility provided by the DNA Adoption team.
  • Your DNA Family A suite of tools for analysing autosomal DNA results. The app currently works with data from 23andMe.

Using manually input data

The output from the equation can be used as Genetic Distance for the Kitsch program within the PHYLIP package. Multiple trees can be combined with the TreeDist program within the PHYLIP package. Works with individual segments in cMs or use the modified equation for total sums in cMs.

Using GEDCOM files

  • DNAGedcom A free utility to compare Ancestry Match files, FTDNA Trees and other Gedcoms for common ancestors. The tool is called GWorks on the DNAGedcom web site.
  • GEDmatch A free utility to compare autosomal DNA data files from all three testing companies and to compare Gedcom files. A number of other very useful free tools are also provided. Additional tools available for a small fee.
  • Learnforever Learn B F Lyons' Exploring Family Trees site allows a user to upload a GEDCOM file to produce a visualisation of pedigree collapse. For further details see the review article The “Exploring Family Trees” Tool by Leah Larkin (The DNA Geek blog, 3 January 2016).

Mobile apps


No longer available/supported/maintained
