Deep data QC
68/100 · DStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
16S amplicon survey of an unspecified metagenome via Illumina MiSeq, producing 15.6 million reads (4.6 billion bases) with moderate quality (87.4% Q20, 83% Q30) and zero N content. Suitable for microbial community profiling and baseline diversity assessment; the 51.8% GC and moderate base fidelity are adequate for OTU/ASV inference with standard quality gatekeeping. The lower Q30 compared to premium amplicon datasets may require more stringent quality filtering, though the read depth compensates and enables reasonable statistical power for dominant taxon abundance estimation.
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.
