systole.interact.Editor#
- class systole.interact.Editor(signal: ndarray, sfreq: int, signal_type: str, corrected_json: str | PathLike = 'corrected.json', figsize: Tuple[int, int] = (15, 7), viewer: Viewer | None = None, corrected_peaks: ndarray | None = None, bad_segments: list | None = None)[source]#
Visualization and manual edition of peaks vectors.
- Parameters:
- signal
The physiological signal.
- sfreq
The sampling frequency of the pysiological signal.
- signal_type
The type of signal that are being analyzed. Can be “PPG”, “ECG” or “RESP”. Defaults to “PPG”.
- corrected_json
Path to the corrected JSON file.
- figsize
The size of the interactive Matplotlib figure for peaks edition. Defaults to (15, 7).
- viewer
The viewer instance from which the editor is called.
- corrected_peaks
The 1d array of corrected peaks indexes, in case the signal was previously edited. This is mostly relevant for the :py:class`systole.interact.Viewer` when a pre-existing JSON file is found in the derivatives.
- bad_segments
List of start_idx and end_idx annotating bad segments, in case the signal was previously edited. This is mostly relevant for the :py:class`systole.interact.Viewer` when a pre-existing JSON file is found in the derivatives.
- Attributes:
- bad_segments
List of start_idx and end_idx listing bad segments. The list is automatically generated by:py:func:systole.utils.norm_bad_segments to avoid overlaping segments.
- uncorrected_peaks
The peaks vector as detected using the default peaks detection algorithm. If the signal was edited previously, this variable is directly imported from the JSON file.
- json_file
Path to the sidecar JSON file.
- peaks
The corrected peaks vector after manual insertion/deletion.
- physio_filePathLike | None
Path to the physiological recording.
- time
Time vector.
- edition_, rejection_, command_box_, save_button_
Widgets controlling the type of modification to perform.

Notes
This module was largely inspired by the peakdet toolbox (physiopy/peakdet).

Methods
__init__(signal, sfreq, signal_type[, ...])find_peaks()Find peaks depending on the signal type.
on_add(xmin, xmax)Add a new peak on the maximum signal value from the selected range.
on_key(event)Undo last span select or quits peak editor.
on_remove(xmin, xmax)Remove peaks by either rejection / deletion, or mark bad segments.
plot_signals()Clear axes and plots data / peaks / troughs.
quit()Quits editor.
save()Save the JSON file.
