Deep data QC
100/100 · AStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
Gut metagenome amplicon sequencing via Illumina MiSeq with 587,106 reads across 24 files at 97.2% Q20 and 89.9% Q30. The 55.9% GC and small total read count suggest modest sampling effort per sample. Users should assess whether the sequencing depth is sufficient for detecting rare operational taxonomic units (OTUs) and whether rarefaction normalization is appropriate given the uneven distribution across samples.
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.
