biobankaccelerometeranalysis's Introduction

biobankAccelerometerAnalysis

A tool to extract meaningful health information from large accelerometer datasets e.g. how much time individuals spend in sleep, sedentary behaviour, and physical activity.

Usage

To extract a summary of movement (average sample vector magnitude) and (non)wear time from raw Axivity .CWA accelerometer files:
python ActivitySummary.py [input_file.CWA] [options]
python ActivitySummary.py sample.cwa

Click here for a sample .CWA file.

The output will look like:

{
    "file-name": "sample.cwa", 
    "file-startTime": "2014-05-07 13:29:50", 
    "file-endTime": "2014-05-13 09:50:25", 
    "pa-overall-avg(mg)": "33.01", 
    "wearTime-overall(days)": "5.80", 
    "nonWearTime-overall(days)": "0.04"
}

Under the hood

We are using a combination of published methods to extract meaningful health information from accelerometer data. [Clicke here for information on the data processing methods on our wiki](https://github.com/aidendoherty/biobankAccelerometerAnalysis/wiki/3.-Methods-Overview)
