What this means
claude:haiku

Lower-coverage whole-genome sequencing of *Caenorhabditis elegans* on HiSeq 2500 with 16.3x coverage (~9.1M reads, 1.63 Gb) and excellent base quality (94.7% Q30), appropriate for bulk population-level SNP discovery or genetic mapping when high-confidence genotyping at all loci is not required. Suitable for natural-variation surveys. Search: *C. elegans*, low-coverage WGS, population genomics.

How this grade was computed
Weighted mean of 4 scored metric(s) → 76/100

The C 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.
