What this means

claude:haiku

454-platform amplicon (Procladius; 449bp reads) grading C (72/100) due to massive 78% duplication and borderline Q30 (81.7%, 58/100 score). The very small dataset (4,652 reads) and extreme duplication render sequence diversity inadequate for reliable OTU/ASV analysis; deep resequencing is recommended.

How this grade was computed

Weighted mean of 2 scored metric(s) → 72/100

The C 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.
