EMGFlow 1.0.1

A general EMG processing and feature extraction package.

EMGFlow

The open workflow for EMG signal processing and feature extraction.

EMGFlow is a Python package for researchers and clinicians to engage in signal processing using the data you have your way. EMGFlow provides a broad range of functions to meet your EMG signal processing needs, without prescribing a specific workflow. With functions to extract over 30 different features according to your needs, EMGFlow provides a uniquely deep feature extraction.

EMGFLow also includes an easy method for producing detailed graphs of EMG signals in large quantities.

Example

As a quick example, the following will create a feature file, starting with a folder of raw data:

import EMGFlow.SignalFilterer as ESIG

# Paths for data files
raw_path = '/data/raw/'          # Raw file contains raw data
notch_path = '/data/notch/'
band_path = '/data/bandpass/'    # Additional files are empty
smooth_path = '/data/smoothed/'
feature_path = '/data/feature/'

# Sampling rate for all files
sampling_rate = 2000

# Filter parameters
notch_vals = [(50, 5)]  # Notch filters to apply (Q, Hz)
band_low = 20           # Low threshold for bandpass filter
band_high = 140         # High threshold for bandpass filter
smooth_window = 50      # Window size for smoothing filter

# Signal analysis
ESIG.NotchFilterSignals(raw_path, notch_path, sampling_rate, notch_vals)
ESIG.BandpassFilterSignals(notch_path, band_path, sampling_rate, band_low, band_high)
ESIG.SmoothFilterSignals(band_path, smooth_path, sampling_rate, smooth_window)
ESIG.AnalyzeSignals(band_oath, smooth_path, feature_path, sampling_rate)
# Will create a "Features.csv" file in feature_path with results
