What this means

claude:haiku

Gut metagenome amplicon sequencing via 454 GS FLX from seven samples totaling 699 million bases (90.7% Q20), supporting bacterial community composition analysis; 454 platform limitations (lower per-sample throughput) typical of mid-2000s microbiome studies.

How this grade was computed

Weighted mean of 2 scored metric(s) → 51/100

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.
