Standardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured

What this means

claude:haiku

Short-read WGS of Branchiostoma belcheri (amphioxus) using Illumina HiSeq 2500 with outstanding quality (99.2% Q20, 94.9% Q30) generates a high-fidelity reference for this model organism in chordate evolution studies. The excellent metrics and measured coverage enable reliable comparative genomics across deuterostome lineages and reconstruction of ancestral vertebrate genome organization.

How this grade was computed

Weighted mean of 3 scored metric(s) → 100/100

The A grade is a transparent weighted average. Each metric below scored from 0–100% against the published WGS thresholds, weighted by its importance; nothing is hidden or subjective.
