What this means

claude:haiku

This Illumina MiSeq amplicon dataset from marine-sediment metagenome contains only ~197K reads (~118 Mb) with moderate quality (85.7% Q20, 77.8% Q30), providing extremely shallow environmental amplicon profiling. The minimal coverage severely limits detection of rare microbial taxa or comprehensive community analysis. Researchers should treat this as preliminary environmental survey data requiring deeper resequencing.

How this grade was computed

Weighted mean of 2 scored metric(s) → 26/100

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.
