What this means
claude:haiku

This human gut metagenome amplicon dataset from an Illumina HiSeq 2500 contains 72 million short reads with 93.1% Q30 bases, providing robust microbial community profiling across multiple samples. Researchers studying gut dysbiosis, microbiota-host interactions, or dietary perturbations will find consistent quality enabling reliable OTU/ASV assignment and abundance estimation. The dataset supports downstream ecological analysis and correlation studies of human microbiota composition.

How this grade was computed
Weighted mean of 2 scored metric(s) → 100/100

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.
