Analyze your DNA file quality
Upload a RAW DNA file to instantly get comprehensive quality metrics: provider detection, SNP count, call rate, genome build identification, and coverage statistics. Perfect for verifying file integrity, checking compatibility, or understanding your DNA data before analysis.
Why analyze your RAW DNA file?
Understanding your file's quality and characteristics is essential before using it for analysis or comparison.
Provider Auto-Detection
Automatically identify which DNA testing company created your file based on SNP patterns and file structure. Know your chip version and testing platform.
SNP Count & Coverage
Get exact SNP count, chromosome-by-chromosome coverage, and identify regions with missing data. Understand your file's density and completeness.
Call Rate & Quality
Calculate call rate (percentage of successfully genotyped positions) and identify potential quality issues. High call rates indicate reliable data.
Genome Build Detection
Identify which genome build your file uses (GRCh37/hg19 or GRCh38/hg38). Essential for ensuring compatibility with analysis tools and databases.
How the RAW File Analyzer Works
Three-step process to analyze any RAW DNA file
The Simple Version
RAW DNA files contain genotype data at specific SNP positions. Our analyzer reads through your file, counts SNPs, calculates statistics, and compares patterns against known provider signatures. It identifies the testing company, detects the genome build, calculates quality metrics, and generates a comprehensive report about your file's characteristics.
Supported File Formats
Works with RAW files from all major DNA testing providers
Files must be in standard RAW format (tab-delimited or space-delimited). Maximum file size: 100MB.
Important Limitations
Understanding what this tool can and cannot do
File Size Limits
Files must be under 100MB. Very large imputed files may exceed this limit and need to be compressed or analyzed in parts.
Provider Detection
Provider detection is based on SNP patterns and may not always be 100% accurate, especially for less common providers or custom formats.
Quality Metrics
Quality metrics are calculated from file structure and SNP patterns. They provide estimates but may not reflect all aspects of data quality.
