Derived from 11,772 genomes: 299 from RefSeq and 11,473 from other sources. For the derivation pipeline and the PASS / WARN / FAIL verdict model, see the methods page for qualibact-v1.1.
QualiBact qualibact-v1.1 thresholds for Haemophilus influenzae, refined from v1.0 based on the Nov 2025 expert-feedback survey.
Two pins on her recommendation:
All other thresholds inherit unchanged from v1.0. WARN tier preserves the engine's tighter values. See the methods page for qualibact-v1.1 for the full pipeline.
Threshold values and rationale for Haemophilus influenzae (qualibact-v1.1) contributed by:
Nov 2025 expert-feedback survey — flagged that >100 contigs are most often contamination, and that two RefSeq references pushing the assembly-size upper bound up have inconclusive ANI (~94 %) against H. influenzae
This table summarises the distribution of each metric, including standard deviation, mean, median, and percentiles.
A combined summary table across all species is available on the summary page.

How to read this: A value outside a failure limit fails QC. Within the failure limits, values beyond a warning limit are borderline and worth a manual look; values within the warning limits pass that criterion. A dash means that no bound is defined on that side.
