What this means
claude:haiku

Fungal amplicon (Acaulospora colombiana, 454 GS FLX+). Grade F, driven by insufficient Q30 bases (70%) and extreme duplication (96.08%). Low Q30 indicates systematic base-calling failure, while near-complete duplication suggests PCR artifacts or sequence collapse. Not recommended for reuse.

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.

Scientific quality

Based on hands-on reproduction of the papers that use this dataset. A reproducible paper that stands on this data is positive evidence; a flagged one is a prompt to look closer — never a verdict on the dataset itself without the evidence.
