What this means

claude:haiku

Oxford Nanopore GridION long-read WGS of Caenorhabditis elegans generated 1.1M reads spanning 9.5 Gb with high coverage (94.7×) but lower per-base accuracy (70.5% Q20). This dataset enables detection of structural variants, complex genomic rearrangements, and repetitive regions that short reads cannot resolve, though base quality requires consensus polishing.

How this grade was computed

Weighted mean of 4 scored metric(s) → 68/100

The D 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.
