What this means

claude:haiku

Amplicon sequencing from soil metagenome on an Illumina MiSeq, producing 1.8 million short reads with moderate quality (45.8% Q30 bases) across 879 million bases. The elevated N-content (2.318%) and balanced GC composition (46.8%) are consistent with environmental amplicon data; enables microbial community profiling with standard filtering.

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.
