1. Introduction to Family Tree DNA Data

Family Tree DNA (FTDNA) is one of the leading genetic genealogy testing companies. Your raw DNA data contains millions of genetic markers that can be used for ancestry research, health predispositions, and connecting with relatives. Downloading your raw data allows you to upload it to third-party platforms like GEDmatch, MyHeritage, Living DNA, and Promethease for additional analysis.

This guide will walk you through downloading three types of DNA data from FTDNA: autosomal DNA (Family Finder), mitochondrial DNA (mtDNA), and Y-DNA (for males).

🧬 Why Download Your Raw DNA Data? Raw data gives you control over your genetic information. You can use it for advanced ethnicity comparisons, chromosome browsers, health reports, and connecting with matches on multiple platforms.

2. Prerequisites Before Downloading

Before you begin the download process, ensure you have the following:

  • ✅ Active FTDNA Account: You must be logged into your Family Tree DNA account.
  • ✅ Completed DNA Test: Your DNA results must be fully processed and available in your account.
  • ✅ Desktop or Laptop Computer: Raw data files are large (10-50 MB) and best downloaded on a computer.
  • ✅ Stable Internet Connection: Required for uninterrupted download.
  • ✅ Sufficient Storage Space: Ensure your device has enough space for the compressed ZIP file.

⚠️ Important: Raw DNA data files contain sensitive genetic information. Only download on trusted devices and store files securely.

3. How to Download Autosomal DNA Data (Family Finder)

Autosomal DNA (Family Finder) tests analyze DNA inherited from both parents, covering approximately 700,000 genetic markers. Follow these steps:

  1. Log into your Family Tree DNA account at www.familytreedna.com.
  2. From your dashboard, click on the "Family Finder" tab under your tested kit.
  3. Look for the "Download Raw Data" button or link in the menu options.
  4. You may be prompted to confirm your identity or agree to a data release consent form.
  5. Select the desired file format: Build 37 (GRCh37) or Build 38 (GRCh38). Most third-party sites accept Build 37.
  6. Click "Download" to save the ZIP file containing your raw data (CSV or TXT format).
  7. Extract the ZIP file to access your raw data file.

💡 Pro Tip: Build 37 is the most compatible format for GEDmatch and other genealogy platforms. Download Build 38 only if specifically required.

4. How to Download mtDNA Data

Mitochondrial DNA (mtDNA) is passed from mother to all children and traces your direct maternal line. Here's how to download it:

  1. Log into your FTDNA account and select your kit.
  2. Click on the "mtDNA" tab from the navigation menu.
  3. Scroll down to the "Download Raw Data" section.
  4. Choose between "FASTA Format" (for academic research) or "CSV Format" (for general analysis).
  5. Click "Download" to save your mtDNA raw data file.
  6. The file contains your full mitochondrial sequence (HVR1, HVR2, and coding region).

🔬 Note: mtDNA raw data is smaller than autosomal data and is typically a text file with your haplogroup and mutation information.

5. How to Download Y-DNA Data

Y-DNA is passed from father to son and traces the direct paternal line. This test is only available for males. Follow these steps:

  1. Log into your FTDNA account and select your kit.
  2. Click on the "Y-DNA" tab.
  3. Navigate to the "Results & Tools" section.
  4. Click on "Download Raw Data" or "Y-STR Values".
  5. Select the desired marker panel (Y-37, Y-67, Y-111, or Big Y).
  6. Choose file format (CSV or Excel format recommended).
  7. Click "Download" to save your Y-DNA data file.

🧬 Note: Big Y customers receive a more comprehensive dataset including SNP mutations and BAM files for advanced analysis.

6. Understanding Raw Data File Formats

Family Tree DNA provides raw data in several formats. Here's what each means:

📄 CSV / TXT Files

Comma-separated values files that can be opened in Excel, Google Sheets, or text editors. These contain SNP calls (rsIDs), chromosome positions, and genotype results (AA, AG, GG, etc.).

📂 ZIP Archives

Raw data is typically compressed into ZIP files to reduce download size. Extract using built-in OS tools or WinZip.

🧬 FASTA Format (mtDNA)

A text-based format for representing nucleotide sequences. Used primarily for academic or research purposes.

📊 BAM Files (Big Y)

Binary Alignment Map files contain detailed sequencing data. Requires specialized software like IGV (Integrative Genomics Viewer) to view.

7. Uploading to Third-Party Sites

Once you've downloaded your raw DNA data, you can upload it to various third-party platforms for additional insights:

  • 🌐 GEDmatch: Free platform for comparing DNA with users from all testing companies. Upload your autosomal data (Build 37) for matching.
  • 🧬 MyHeritage DNA: Upload raw data for free ethnicity estimates and relative matching.
  • ⚕️ Promethease: Generate health and trait reports from your raw DNA data ($12 fee).
  • 🌍 Living DNA: Upload for additional regional ancestry breakdowns.
  • 🔬 DNA Painter: Visualize chromosome mapping and segment data.

⚠️ Privacy Reminder: Always review the privacy policies of third-party sites before uploading your genetic data. Some platforms may share anonymized data with researchers.

8. Troubleshooting Download Issues

Having trouble downloading your raw DNA data? Try these solutions:

❌ "Download Raw Data" Button Missing

Solution: Your results may not be fully processed. Autosomal DNA typically takes 2-4 weeks after the lab receives your sample. Check your dashboard for processing status.

❌ File Won't Extract

Solution: The ZIP file may be corrupted. Try downloading again using a different browser. Use 7-Zip (Windows) or The Unarchiver (Mac) for extraction.

❌ Third-Party Site Rejects My File

Solution: Ensure you downloaded the correct Build version (Build 37). Some sites require specific file formatting. Use a conversion tool if needed.

❌ Download Takes Too Long

Solution: Raw data files can be large (50-100 MB for Big Y). Use a wired internet connection instead of Wi-Fi for faster downloads.

9. DNA Data Security & Privacy Tips

Your raw DNA data is extremely sensitive. Follow these security best practices:

  • 🔒 Store Files Encrypted: Use password-protected folders or encrypted drives to store raw data files.
  • 🗑️ Delete After Use: If you no longer need the file, securely delete it using file shredder software.
  • 📧 Never Email Raw Data: Email is not secure for transmitting genetic files. Use secure file transfer services instead.
  • 🔐 Use Strong Passwords: Protect your FTDNA account with a unique, strong password and enable two-factor authentication.
  • 📖 Review Third-Party Policies: Before uploading to any site, read their data retention and sharing policies carefully.

🔐 Did You Know? Family Tree DNA allows you to delete your raw data from their servers at any time. Go to Account Settings → Privacy → Delete Raw Data.
