Deep data QC
66/100 · DStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
Mixed culture amplicon sequencing via 454 GS FLX Titanium with only 5,310 reads and 2.6 million bases, making this an exceptionally small dataset. The read type is unknown (low confidence). While the 93.5% Q20 and 79.9% Q30 are decent, the ultra-low sequencing volume severely limits community representation. Users should verify whether this pilot dataset is suitable for exploratory analysis or requires resequencing for any quantitative claims.
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.
