Deep data QC
64/100 · DStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
16S/18S amplicon sequencing of human gut metagenome on an Illumina MiSeq generates ~2.8 million reads at moderate base quality (90.4% ≥Q20, 79.1% ≥Q30), enabling microbial community composition analysis and taxonomic assignment. The substantial read count supports robust diversity assessment. Reuse for alpha diversity and community comparison requires rarefaction and normalization.
The D 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.
