Can I convert VCF to RAW for any purpose?

Yes, but there are important considerations about VCF to RAW conversion:

Valid Use Cases:

1. Platform Compatibility:

• Converting WGS-derived VCF to use on ancestry sites
• Making data compatible with 23andMe, AncestryDNA formats
• Enabling upload to genealogy platforms
• Using with third-party analysis tools

2. Data Management:

• Reducing file size for easier handling
• Standardizing format across family members
• Creating backups in different formats
• Sharing with relatives in accessible format

3. Analysis Tools:

• Using tools that require RAW format
• Running calculators expecting consumer DNA format
• Third-party ancestry analysis
• Trait prediction tools

Important Limitations:

VCF Files Have Restrictions:

• Variant-Only: VCF files typically only include variations, not all positions
• Coverage Varies: May not have all SNPs needed for some analysis
• Quality Dependent: Accuracy depends on original sequencing quality
• Not All Equal: WGS VCF ≠ SNP array VCF

Special Considerations:

For WGS-Derived VCF Files:

• Excellent source material
• High quality and comprehensive
• RAW conversion works very well
• Recommended for ancestry use

For SNP Array VCF Files:

• May have limited usefulness
• Already in restricted format
• Conversion may not add value
• Check original source

NOT Recommended For:

• MyHeritage/FTDNA/LivingDNA Compatibility: These platforms work best with WGS to RAW service
• Medical Decision Making: VCF conversions should not replace direct testing
• Clinical Diagnosis: Use proper clinical testing instead
• Low-Quality VCF: Poor input = poor output

Our Service:

Our VCF to RAW service is designed for:

• Individuals with WGS tests (Nebula, Dante, YSEQ)
• Those needing file conversion for analysis tools
• Research and educational purposes
• Genealogy applications

However, we strongly recommend:

• If you have BAM/CRAM files, use "WGS to RAW" service instead
• WGS to RAW provides better quality and compatibility
• VCF to RAW is a secondary option when BAM/CRAM unavailable

Before Converting:

• Verify your VCF file origin and quality
• Understand what data it contains
• Consider if conversion will meet your needs
• Check if original BAM/CRAM files are available
