What this means
claude:haiku

This Drosophila melanogaster whole-genome sequencing dataset generated on the Illumina Genome Analyzer II platform yields 16.8 million reads (2.52 billion bases) with an extrapolated genome coverage of approximately 18× and moderate quality scores (76% Q20 bases). The dataset is findable by organism (D. melanogaster), classic sequencing platform, and WGS application. For comprehensive genomic analyses like structural variant calling or de novo assembly, the moderate coverage and quality may have limitations compared to modern sequencing.

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.
