Cue light analyzer

class simba.data_processors.cue_light_analyzer.CueLightAnalyzer(config_path, data_dir, cue_light_names, save_dir=None, core_cnt=- 1, detailed_data=False, verbose=True)

Bases: simba.mixins.config_reader.ConfigReader

Analyze when cue lights are in ON and OFF states. Results are stored in the project_folder/csv/cue_lights cue lights directory.

Parameters

• config_path (Union[str, os.PathLike],) – path to SimBA project config file in Configparser format

• data_dir (Union[str, os.PathLike],) – directory holding pose-estimation data. E.g., project_folder/csv/outlier_corrected_movement_location

• cue_light_names (List[str]) – Names of cue light ROIs, as defined in the SimBA ROI interface.

Example

>>> cue_light_analyzer.run()

Cue light classification statistics

class simba.data_processors.cue_light_clf_statistics.CueLightClfAnalyzer(config_path, cue_light_names, clf_names, data_dir=None, pre_window=0, post_window=0)

Bases: simba.mixins.config_reader.ConfigReader

Compute aggregate statistics when classified behaviors are occurring in relation to the cue light ON and OFF states.

Parameters

• config_path (Union[str, os.PathLike]) – path to SimBA project config file in Configparser format

• pre_window (int) – Time period (in millisecond) before the onset of each cue light to compute aggregate classification statistics within.

• post_window (int) – Time period (in millisecond) after the offset of each cue light to compute aggregate classification statistics within.

• cue_light_names (List[str]) – Names of cue lights, as defined in the SimBA ROI interface.

• list (List[str]) – Names of the classifiers we want to compute aggregate statistics for.

Example

>>> test = CueLightClfAnalyzer(config_path=r"C:     roubleshooting\cue_light        1\project_folder\project_config.ini",
>>>                            pre_window=1,
>>>                            post_window=1,
>>>                            cue_light_names=['cl'],
>>>                            clf_names=['freeze'])
>>> test.run()
>>> test.save()

Cue light movement statistics

class simba.data_processors.cue_light_movement_statistics.CueLightMovementAnalyzer(config_path, cue_light_names, bp_name, data_dir=None, pre_window=0, post_window=0, verbose=True)

Bases: simba.mixins.config_reader.ConfigReader

Compute aggregate statistics of animal movement in relation to the cue light ON and OFF states.

Parameters

• config_path (str) – path to SimBA project config file in Configparser format

• pre_window (int) – Time period (in millisecond) before the onset of each cue light to compute aggregate classification statistics within.

• post_window (int) – Time period (in millisecond) after the offset of each cue light to compute aggregate classification statistics within.

• cue_light_names (List[str]) – Names of cue lights, as defined in the SimBA ROI interface.

• threshold (float) – The body-part post-estimation probability threshold. SimBA omits movement calculations for frames where the body-part probability threshold is lower than the user-specified threshold.

>>> test = CueLightMovementAnalyzer(config_path=r"C:        roubleshooting\cue_light        1\project_folder\project_config.ini",
>>>                                 pre_window=0,
>>>                                 post_window=0,

Cue light plotting

class simba.plotting.cue_light_visualizer.CueLightVisualizer(config_path, cue_light_names, video_path, data_path, frame_setting=False, video_setting=True, core_cnt=- 1, show_pose=True, verbose=True)

Bases: simba.mixins.config_reader.ConfigReader

Visualize SimBA computed cue-light ON and OFF states and the aggregate statistics of ON and OFF states.

Parameters

• config_path (str) – path to SimBA project config file in Configparser format.

• cue_light_names (List[str]) – Names of cue lights, as defined in the SimBA ROI interface.

• video_path (str) – Path to video which user wants to create visualizations of cue light states and aggregate statistics for.

• frame_setting (bool) – If True, creates individual frames in png format. Defaults to False.

• video_setting (bool) – If True, creates compressed videos in mp4 format. Defaults to True.

Examples

>>> cue_light_visualizer = CueLightVisualizer(config_path='SimBAConfig', cue_light_names=['Cue_light'], video_path='VideoPath', video_setting=True, frame_setting=False)
>>> cue_light_visualizer.run()
