What this means
claude:haiku

This D. melanogaster WGS dataset from the Illumina Genome Analyzer II platform contains 21.6 million reads (3.24 billion bases) with extrapolated 23.1× coverage and good quality (83.4% Q20, 58.4% Q30 bytes). The dataset supports searches for Drosophila whole-genome sequencing, Genome Analyzer II, and moderate-depth resequencing projects. While adequate for SNP discovery, the Q30 performance (58.4%) suggests some caution with high-confidence structural variant calls.

How this grade was computed
Weighted mean of 4 scored metric(s) → 56/100

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.
