Deep data QC
93/100 · AStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
16S amplicon profiling of feces metagenome via Illumina MiSeq, yielding 1.9 million reads (1.05 billion bases) with moderate quality (95.1% Q20, 87.9% Q30) and minimal N-content (0.005%). Provides basic compositional and diversity profiling of intestinal bacterial communities; the 53.8% GC reflects typical fecal microbiota. The smaller read volume limits statistical power for rare taxon detection, but the moderate base quality is acceptable for identifying dominant community members and primary dysbiosis patterns with standard preprocessing.
The A 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.
