Deep data QC
63/100 · DStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
Human metagenome amplicon sequencing via 454 GS FLX Titanium with 789,400 reads and 295 million bases at modest quality (93.4% Q20, 78.9% Q30). The longer read length inherent to 454 pyrosequencing allows better phylogenetic resolution but lower per-base accuracy. Users should note the read type is unknown (low confidence) and verify whether this older-platform data is compatible with modern bioinformatic pipelines designed for Illumina amplicons.
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.
