What this means
claude:haiku

Zebu cattle WGS on HiSeq 2000 generated 31 million 99.4 bp reads at 97.8% Q20 and 91.4% Q30, indicating higher per-base quality than SRR4279980 despite lower total yield. The 43.5% GC aligns with mammalian genomes; adequate coverage for mapping and SNP calling in livestock breeding or evolutionary studies with moderate sequencing depth.

How this grade was computed
Weighted mean of 3 scored metric(s) → 100/100

The A 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.

Scientific quality

Based on hands-on reproduction of the papers that use this dataset. A reproducible paper that stands on this data is positive evidence; a flagged one is a prompt to look closer — never a verdict on the dataset itself without the evidence.
