What this means
claude:haiku

This D. melanogaster WGS dataset from the Illumina Genome Analyzer II platform contains 37.2 million reads (5.57 billion bases) with high extrapolated coverage (39.8×) and good quality (82.4% Q20, 61.7% Q30 bytes). The substantial read depth enables variant discovery across the genome. Search terms: Drosophila whole-genome sequencing, Genome Analyzer II, population genomics, resequencing, supporting SNP mapping and comparative studies.

How this grade was computed
Weighted mean of 4 scored metric(s) → 63/100

The D 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.
