Python toolkit for neurophysiological signal processing: ECG (HR, HRV, R-peaks), EEG (complexity, PSD), EMG (activation onset), EDA/GSR (SCR decomposition), PPG, and RSP. Includes synthetic signal simulation. Alternatives: BioSPPy (less maintained), MNE (EEG/MEG specialist), heartpy (ECG only), scipy.signal (raw DSP).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# NeuroKit2
## Overview
NeuroKit2 provides a unified, high-level API for physiological signal processing. Each modality (ECG, EEG, EMG, EDA, PPG, RSP) follows the same `nk.{signal}_process()` → `nk.{signal}_analyze()` workflow: raw signal in, cleaned signal + features out. The library handles detrending, filtering, peak detection, artifact correction, and feature extraction automatically, with parameters tuned to biosignal characteristics. Results are returned as pandas DataFrames, making downstream statistics straightforward. NeuroKit2 also provides `nk.{signal}_simulate()` functions for generating synthetic test signals.
## When to Use
- Extracting HRV (heart rate variability) features from ECG recordings for stress or autonomic nervous system analysis
- Detecting R-peaks in ECG and computing RR intervals, SDNN, RMSSD, pNN50, LF/HF ratio
- Processing EDA/GSR signals to separate tonic (SCL) and phasic (SCR) components for psychophysiology research
- Cleaning and segmenting EMG signals for muscle onset/offset detection in biomechanics
- Processing PPG signals from wearable sensors as ECG surrogates for heart rate and SpO2

How to install
mdr add jaechang-hits/sciagent-skills/neurokit2@sha256:269dbc465cdc543aThe line at the top of this page pins the label git:20260428.81ea2d2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
