Deep data QC
100/100 · 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 HiSeq 2500, producing 957,000 reads (463 million bases) with excellent quality (97.8% Q20, 95.8% Q30) and the typical 54.5% GC of fecal bacterial communities. Suitable for baseline microbiota composition surveys and preliminary diversity assessment; the high base quality and zero N-content enable reliable taxonomy assignment despite the smaller read count. Moderate read volume provides adequate power for abundance estimation of dominant taxa but may limit statistical resolution of rare biosphere members.
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.
