What this means

claude:haiku

Illumina Genome Analyzer IIx whole-genome sequencing of Drosophila melanogaster, generating 5.2 billion bases at estimated 37.8x coverage with moderate quality (90.9% Q20, 82.8% Q30). This dataset is suitable for variant discovery and genome annotation, though the quality profile recommends filtering for high-confidence variants.

How this grade was computed

Weighted mean of 4 scored metric(s) → 88/100

The B grade is a transparent weighted average. Each metric below scored from 0–100% against the published WGS thresholds, weighted by its importance; nothing is hidden or subjective.
