What this means

claude:haiku

Marine metagenome amplicon sequencing via 454 GS FLX generating 89 million bases (99.1% Q20), enabling targeted 16S or 18S profiling of ocean microbiota; modest total yield reflects lower sample number typical of 454-era studies.

How this grade was computed

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

The A 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.
