Deep data QC
82/100 · BStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
Long-read amplicon (454 GS FLX Titanium, aquatic metagenome); grade-B (score=82/100) despite extreme measured duplication (98.19%), which is typical for amplicon/metagenomic sequencing and not penalized as heavily here. Base quality is excellent (Q30=84.6%, base quality=35.9); duplication does not impair taxonomic profiling or allele-abundance estimates.
The B 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.
