Required python packages:

• numpy: 1.9.2
• scipy: 0.14.0
• pandas: 0.16.0
• sklearn: 0.16.1
• pickle
• matplotlib: 1.3.1
• imp
• PyWavelets: 0.2.2
• os

To run artifact detection from the command line:

python EDA-Artifact-Detection-Script.py

Note that PickleDirectory is the main directory

Currently there are only 2 classifiers to choose from: Binary or Multiclass

To run peak detection:

python EDA-Peak-Detection-Script.py

Descriptions of the algorithm settings can be found at http://eda-explorer.media.mit.edu/info/

To run accelerometer feature extraction:

python AccelerometerFeatureExtractionScript.py

This file works slightly differently than the others in that it gives summary information over periods of time.

Notes:

1. Currently, these files are written with the assumption that the sample rate is an integer power of 2.

2. Keep the "classify.py" and "SVMBinary.p" and "SVMMulticlass.p" files in the same directory.
