What this means

claude:haiku

This algae metagenome amplicon-seq from Illumina HiSeq 2000 generated 525.4 million short reads (63.1 gigabases) with high quality (98% Q20, 88.6% Q30) and 52.2% GC. The massive scale supports deep profiling of algal community composition and abundance estimation in environmental samples.

How this grade was computed

Weighted mean of 2 scored metric(s) → 95/100

The A grade is a transparent weighted average. Each metric below scored from 0–100% against the published amplicon thresholds, weighted by its importance; nothing is hidden or subjective.
