What this means
claude:haiku

This D. melanogaster WGS dataset from the Illumina Genome Analyzer II platform contains 13.6 million reads (2.04 billion bases) with extrapolated 14.6× coverage and moderate quality (83.3% Q20, 57% Q30 bases). The dataset is searchable by classic Genome Analyzer II sequencing, lower-coverage WGS, and Drosophila genomics. While the depth and quality are sufficient for SNP discovery, the moderate coverage may limit confidence in structural variant detection or comprehensive variant annotation.

How this grade was computed
Weighted mean of 4 scored metric(s) → 41/100

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.
