Deep data QC
53/100 · FStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
16S rRNA amplicon profiling of human gut microbiota via Illumina MiSeq, yielding 1.8 million reads (1.1 billion bases) with moderate quality (93.6% Q20, 85.8% Q30) and the typical 53.3% GC of fecal communities. Supports basic alpha/beta diversity assessment and bacterial composition tracking; the lower Q30 compared to premium amplicon datasets may necessitate more stringent quality gatekeeping before ASV/OTU clustering. Adequate read depth for dominant taxon identification but statistical power for rare taxa may be limited.
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.
