neurokit2 0.0.3

The Python Toolbox for Neurophysiological Signal Processing.

The Python Toolbox for Neurophysiological Signal Processing (EDA, ECG, PPG, EMG, EEG…)

This is a work in progress project meant as a continuation of NeuroKit.py. We are looking to build a community of people around this collaborative project. If you’re interested by getting involved, do let us know!

Installation

To install NeuroKit, run this command in your terminal:

pip install https://github.com/neuropsychology/neurokit/zipball/master

Examples

Simulate biosignals

import numpy as np
import pandas as pd
import neurokit2 as nk

# Generate synthetic signals
ecg = nk.ecg_simulate(duration=10, heart_rate=70)
rsp = nk.rsp_simulate(duration=10, respiratory_rate=15)
eda = nk.eda_simulate(duration=10, n_peaks=3)
emg = nk.emg_simulate(duration=10, n_bursts=2)

# Visualise biosignals
data = pd.DataFrame({"ECG": ecg,
                     "RSP": rsp,
                     "EDA": eda,
                     "EMG": emg})
data.plot(subplots=True, layout=(4, 1))

Signal processing

NeuroKit includes functions to facilitate signal processing:

• signal_binarize(): Convert a continuous signal into zeros and ones depending on a given threshold.

• signal_findpeaks(): Locate peaks (local maxima) in a signal and their related characteristics, such as height (prominence), width and distance with other peaks.

• signal_resample(): Up- or down-sample a signal.

• signal_interpolate(): Interpolate (fills the values between data points) a signal using different methods.

• signal_detrend(): Apply a baseline (order = 0), linear (order = 1), or polynomial (order > 1) detrending to the signal (i.e., removing a general trend).

• signal_filter(): Apply a lowpass, highpass or bandpass filter to the signal.

• signal_merge(): Arbitrary addition of two signals with different time ranges.
