How to Download and Analyze Your Raw DNA Data: Complete Guide

Your DNA data is yours to own. Once you've tested with 23andMe, AncestryDNA, MyHeritage, or other companies, you can download your raw DNA data and analyze it with third-party tools for even deeper insights into your ancestry.

This complete guide walks you through downloading your raw DNA file and using advanced analysis tools to unlock more detailed information about your heritage.

What is Raw DNA Data?

Raw DNA data is your unprocessed genetic information — the actual results from sequencing your DNA sample. When you test with a company like 23andMe or AncestryDNA, they:

1. Extract DNA from your saliva sample
2. Sequence your entire genome (or the important parts)
3. Compare it to their reference databases
4. Generate reports and results
5. Store your raw data in their system

The "raw data" is the genotype file — usually a .txt or .csv file containing your genetic markers at specific positions across all 23 chromosome pairs.

Why Download Raw DNA Data?

Your DNA data can be analyzed by multiple companies and tools, each using different reference populations and algorithms. By downloading your raw data, you can:

• Find more relatives: Different sites have different user databases, so you'll match with new people
• Get deeper ancestry analysis: Specialized tools like Helixline provide more granular regional breakdowns
• Discover phasing: Understand which DNA came from which parent
• Perform genealogical research: Use DNA Painter and other genealogy tools to map your family tree
• Advanced haplogroup analysis: Get more detailed information about your ancestral lineages
• Keep your data secure: Download your data and store it personally

Understanding Your Raw DNA File

When you download your raw data, you'll get a file that looks something like this:

rsid    chromosome    position    genotype
rs3131972    1    752566    AG
rs12562034    1    768448    AG
rs12124819    1    776546    AA
rs11240777    1    798959    GG

What Each Column Means

• rsid: Reference SNP ID — a unique identifier for this genetic marker
• chromosome: Which chromosome (1-22 or X, Y, MT)
• position: Where on the chromosome in base pairs
• genotype: Your nucleotides at that position (AA, AG, GG, AT, etc.)

Your raw data typically contains 500,000 to 1,000,000 genetic markers depending on which test you took.
