Genetic Genealogy Data Types

Type of Data

What it is

Why it’s Useful

Chromosome Browser (CB)

A chromosome browser shows you specifically where you share DNA with your match – the amount and on which chromosome. This data can be displayed in a either a graphical or an alphanumerical format.

This tool is your primary document for comparing your matches to see which ones also share overlapping segments of DNA

Comma-separated Value Files (CSV)

A generic computer file format containing data that can be imported into different applications (like GEDCOMs) and formatted. CSV files are most commonly used to import data into spreadsheets and databases.

Many of the files you will use are in CSV files so that they can be opened in different applications, much like GEDCOMs.


Family trees in a computer file format that can be used by most genealogy programs, including GEDCOM (pronounced JED-com), is short for Genealogical Data COMmunication.

GEDCOMs provide multiple clues to aid your search. They contain surnames, lineages of your matches, and perhaps even the name of your ancestors! When you have two ICW matches with GEDCOMs, you can potentially figure out who your ancestor is by identifying common their ancestor.

In Common With (ICW)

An ICW, or “In Common With” match is related to both you and at least one of your other matches.

This indicates that your relationship with your match is on the same side of your family tree, making ICW matches ideal candidates for triangulation.

Match Data

All the information available about your matches - their names, contact information, predicted relationship with you, amount of shared DNA, family surnames, family trees, etc.

Match data can help you determine if a match is a good candidate for triangulation.

Overlapping Segments of DNA

The inherited DNA you and your match(es) share, indicating you descend from the same ancestor. You and your matches are almost always related. However, other matches who also share the same overlapping segments of DNA may not be related to each other.

These help you identify which matches also share the same segments with each other to see if they are ICW. If they are ICW, then you are all likely related on the same side of your tree.

Raw Data

This is the information provided by a sample of your saliva – some 700,000 pieces of data – before it is analyzed by your testing company’s proprietary software.

Raw data can be downloaded from each testing company and processed by different tools and utilities. You can even upload your raw data from one testing company to another if they used the same test chip.


Last names.

Surnames are clues that also help you identify your common ancestors. This is particularly true for males, whose surnames rarely change from generation to generation.



  1. 1.       Generate your FTDNA Data Files on DNAGEDCOM will gather all of your FTDNA match data and format it into files that can be opened as spreadsheets.


  1. Select the Family Tree DNA link and then select “Download Family Tree DNA Data.”

Enter your FTDNA kit number and password. This is the same kit number and password you enter when you log in to Family Tree DNA. Note: Your FTDNA password is never stored or shared.

Click the “Get Data” button at the bottom of the screen.  Generating your data files can take up to two hours depending on how many matches you have and how many have posted their family trees.

Extract and Download FTDNA Data Files from

1)      After generates your data, the compressed file will not automatically download to your PC, you will need to go to your Members/View Files to download your zip file. Usually it will go to the folder called “Downloads.” This “zipped” file actually contains three files: your chromosome browser data, your Family Finder matches and your ICW file.

Tip: A *.zip or *.gz file temporarily shrinks files so that they can be transmitted faster. These compressed files have to be “unzipped” to open them. 

2)      Unzip this file to the directory of your choice. Right-click on the .zip file and select “Extract All” (Or skip down to Step 3 to download these files already unzipped.).

All three files will have the *.csv extension and begin with your FTDNA kit number.


3)      If you prefer not to work with *.zip files, you can download the uncompressed files directly from, which stores a copy of your data files on its servers as a backup free of charge.

Hover your cursor over the “Members” link in the menu bar, and scroll down to “View Files” from the drop-down menu that appears.

Your data files are all located in the FTDNA folder on the left-side of the screen. Double-click on the folder containing your FTDNA kit number. Your data files will then appear on the right-side of the screen.

Hold down the CTRL key on your keyboard and click on the files you want to download with your left mouse button to highlight them. Once highlighted, click on the files again with your right mouse button (not the left one!) and select “Download” to download them to your PC.
