What this means
claude:haiku

16S/18S amplicon sequencing of human gut metagenome on an Illumina MiSeq generates ~2.8 million reads at moderate base quality (90.4% ≥Q20, 79.1% ≥Q30), enabling microbial community composition analysis and taxonomic assignment. The substantial read count supports robust diversity assessment. Reuse for alpha diversity and community comparison requires rarefaction and normalization.

How this grade was computed
Weighted mean of 2 scored metric(s) → 64/100

The D 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.
