# Targets config workflow reference
This page summarizes the target-definition configuration used by batdetect2.
## `TargetConfig`
Defined in `batdetect2.targets.config`.
Fields:
- `detection_target`: one `TargetClassConfig` defining detection eligibility.
- `classification_targets`: list of `TargetClassConfig` entries for class
encoding/decoding.
- `roi`: ROI mapping config with `default` mapper and optional per-class
`overrides`.
## `TargetClassConfig`
Defined in `batdetect2.targets.classes`.
Fields:
- `name`: class label name.
- `tags`: tag list used for matching (shortcut for `match_if`).
- `match_if`: explicit condition config (`match_if` is accepted as alias).
- `assign_tags`: tags used when decoding this class.
`tags` and `match_if` are mutually exclusive.
## Supported condition config types
Built from `batdetect2.data.conditions`.
- `has_tag`
- `has_all_tags`
- `has_any_tag`
- `duration`
- `frequency`
- `all_of`
- `any_of`
- `not`
## ROI mapper config
`roi.default` and each `roi.overrides.<class_name>` entry support built-in
mappers including:
- `anchor_bbox`
- `peak_energy_bbox`
Key `anchor_bbox` fields:
- `anchor`
- `time_scale`
- `frequency_scale`
Top-level ROI mapping shape:
- `default`: fallback mapper used for all classes.
- `overrides`: optional mapping from class name to mapper config.
