What this means
claude:haiku

Illumina Genome Analyzer IIx whole-genome sequencing of Drosophila melanogaster with 5.7 billion bases at estimated 41.1x coverage and moderate quality (92.6% Q20, 84.4% Q30). The dataset is suitable for variant discovery and genome annotation applications, though the Q30 percentage indicates value in quality-based read trimming before analysis of variants with low allelic frequencies.

How this grade was computed
Weighted mean of 4 scored metric(s) → 91/100

The A 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.
