What this means

claude:haiku

Whole-genome sequencing (Staphylococcus epidermidis, 454 GS FLX Titanium platform). Grade C, platform and Q30 constraints present. Q30 of 79.7% is the critical limitation (48/100 score)—below standards for variant accuracy. The 454 platform produces longer reads (320.5 bp) but compromised base quality makes variant reuse risky. All metrics measured.

How this grade was computed

Weighted mean of 3 scored metric(s) → 73/100

The C 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.
