What this means
claude:haiku

This Illumina MiSeq amplicon dataset from human metagenome samples comprises 8.6 million short reads spanning 4.3 billion bases with moderate quality (76.4% Q20, 65.7% Q30), enabling targeted microbial community profiling at species/operational taxonomic unit resolution. The 56.4% GC content and read-count depth support diversity assessment and taxonomic binning in gut or environmental microbiota. Reusers should verify the specific amplicon target (marker gene) and confirm read-length adequacy for discriminating closely related taxa, as quality metrics suggest acceptable but not exceptional fidelity for rare-variant calling.

How this grade was computed
Weighted mean of 2 scored metric(s) → 33/100

The F 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.
