What this means

claude:haiku

Illumina HiSeq 2500 whole-genome shotgun sequencing of marine sediment metagenome generated 13.6M reads with exceptional quality (97% Q30 bases, 43.4% GC) and minimal N-content. This environmental DNA dataset enables comprehensive profiling of microbial community composition, functional gene diversity, and metabolic potential in ocean microbiota without prior cultivation.

How this grade was computed

Weighted mean of 3 scored metric(s) → 86/100

The B 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.
