Deep data QC
34/100 · FStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
Illumina MiSeq 16S/18S amplicon profiling of human gut microbiota yields 7.6 billion bases at 80.9% Q20 across 15.3 million reads. Adequate for taxonomic composition analysis; lower Q-scores typical of amplicon sequencing but manageable for operational taxonomic unit/amplicon sequence variant calling.
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.
