What this means
claude:haiku

This D. melanogaster WGS dataset from the Illumina Genome Analyzer II platform contains 16.8 million reads (2.52 billion bases) with extrapolated 18× coverage and moderate quality (77.5% Q20, 48.7% Q30 bytes). The dataset supports SNP discovery searches though moderate coverage and Q30 scores suggest caution with structural variant calls. Search terms: Drosophila WGS, Genome Analyzer II, lower-coverage genomics.

How this grade was computed
Weighted mean of 4 scored metric(s) → 47/100

The F 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.
