What this means
claude:haiku

This Illumina HiSeq 2000 amplicon dataset from human gut metagenome samples provides 39.6 million reads and 7.8 billion bases with moderate quality (78.7% Q20, 63.5% Q30) at 55.7% GC content, supporting microbial community composition analysis and relative-abundance estimation. The amplicon-based approach resolves operational taxonomic units suitable for diversity profiling and treatment-response studies across individuals. Reusers should account for quality metrics limiting low-abundance taxon detection and de novo assembly compared to shotgun metagenomics approaches.

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.
