What this means
claude:haiku

This D. melanogaster WGS dataset from the Illumina Genome Analyzer II platform contains 17.8 million reads (3.38 billion bases) with extrapolated 24.2× coverage and good quality (80.6% Q20, 68.5% Q30 bases). The dataset is searchable by Drosophila whole-genome sequencing, Genome Analyzer II, and offers reasonable depth for variant mapping. Notably, this sample shows elevated Q30 performance (68.5%) relative to some Genome Analyzer II runs, enhancing confidence in called variants.

How this grade was computed
Weighted mean of 4 scored metric(s) → 57/100

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.
