Deep data QC
61/100 · DStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
Human gut metagenome amplicon-seq on MiSeq generates 7.6 billion bases (12.7 million reads) with moderate quality (78.2% Q30 bases), suitable for microbiota composition profiling. The dataset provides good sample coverage for assessing microbial diversity; moderate quality is typical for amplicon surveys and sufficient for OTU-level or species-level taxonomic assignment.
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.
