How to tune detection threshold

Use this guide to compare detection outputs at different threshold values.

1) Start with a baseline run

Run an initial prediction workflow and keep outputs in a dedicated folder.

2) Sweep threshold values

If you use the legacy detect command, run multiple thresholds (for example, 0.1, 0.3, 0.5) and compare output counts and quality on a validation subset.

3) Validate against known calls

Use files with trusted annotations or expert review to select a threshold that fits your project goals.

4) Record your chosen setting

Write down the chosen threshold and rationale so analyses are reproducible.

For conceptual trade-offs, see {doc}../explanation/model-output-and-validation.
