Deep data QC
52/100 · FStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
Human gut metagenome amplicon sequencing via Illumina MiSeq with 12.7 million reads and 6.36 billion bases but notably lower quality (83.3% Q20, 75.7% Q30) and 51.8% GC. The reduced base accuracy may increase false-positive OTU assignment or inflate richness estimates due to sequencing errors. Consider aggressive quality filtering and chimera-removal strategies before trusting low-abundance community members.
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.
