What this means
claude:haiku

Human RNA-seq from a Helicos HeliScope platform (single-molecule sequencing technology) with 62 million reads at 0% Q30, indicating the platform does not report traditional quality scores. The dataset represents rare high-throughput single-molecule transcriptome data.

How this grade was computed
Weighted mean of 3 scored metric(s) → 57/100

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