Deep data QC
91/100 · AStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
Metagenome amplicon sequencing via Illumina MiSeq with 2 million reads and 1.18 billion bases at good quality (95.2% Q20, 87.4% Q30). The 56.2% GC and 24 files suggest directed amplicon profiling, though source is unspecified. Users should clarify the amplicon target and environmental source; modest read depth may limit rare-OTU detection depending on sample complexity.
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.
