What is this DNA file?

Choose a raw DNA or genome file. The inspector reads a small amount of file data locally in your browser to identify common formats and visible metadata. It does not upload the selected file.

For privacy and performance, the inspector reads only local file data required for format detection. Large BAM/CRAM/FASTQ files are identified rather than fully parsed.

What it recognizes

A file-format translator for normal humans.

FormatWhat it usually containsTypical role
VCFCalled variants plus metadataDownstream annotation and analysis
FASTQRaw sequencing reads + quality scoresStarting point for alignment and variant calling
BAM / CRAMReads aligned to a reference genomeVisualization, re-calling, quality review
Consumer TXT / CSVSelected SNP genotypesAncestry, matching and compatible research tools
A file type cannot tell you whether a finding is medically true. Raw calls can contain errors; interpretations can conflict; clinically important findings may need professional interpretation and confirmation.
