What this means
claude:haiku

This D. melanogaster WGS dataset from the Illumina Genome Analyzer II platform contains 20.3 million reads (3.05 billion bases) with extrapolated 21.8× coverage and moderate quality (70.6% Q20, 48.7% Q30 bytes). The high N-content (4.858%) suggests possible sample contamination or systematic sequencing issues. Searchable by Drosophila WGS, Genome Analyzer II, this dataset requires pre-alignment QC filtering and may be better suited for SNP discovery than assembly work.

How this grade was computed
Weighted mean of 4 scored metric(s) → 53/100

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.
