Deep data QC
34/100 · FStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
Targeted bacterial 16S amplicon sequencing via Illumina MiSeq, yielding 875,000 reads from 439 million total bases with notably lower Q30 accuracy (70.3%) and elevated GC content (56%). Suitable for preliminary microbial community surveys or taxonomic screening; the reduced base quality may necessitate more aggressive QC and chimera-removal steps during amplicon analysis. The sparse read count limits statistical power for rare taxa detection or high-resolution community clustering.
The F 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.
