pyActigraphy

Open-source python package for actigraphy data analysis.

This package is meant to provide a comprehensive set of tools to:

• read actigraphy raw data files with various formats
• calculate typical wake/sleep cycle-related variables (ex: IS, IV, ...)
• perform complex analyses (ex: FDA, SSA, HMM, ...)

Requirements

• python 3.X
• joblib
• pandas
• numba
• numpy
• pyexcel
• pyexcel-ods3
• scipy
• statsmodels

Installation

In a (bash) shell, simply type:

• For users:

pip install pyActigraphy

To update the package:

pip install -U pyActigraphy

It is strongly recommended to use the latest version of the pyActigraphy package.

• For developers:

git clone git@github.com:ghammad/pyActigraphy.git
cd pyActigraphy/
git checkout develop
pip install -e .

Quick start

The following example illustrates how to calculate the interdaily stability with the pyActigraphy package:

>>> import pyActigraphy
>>> rawAWD = pyActigraphy.io.read_raw_awd(fpath + 'SUBJECT_01.AWD')
>>> rawAWD.IS()
0.6900175913031027
>>> rawAWD.IS(freq='30min', binarize=True, threshold=4)
0.6245582891144925
>>> rawAWD.IS(freq='1H', binarize=False)
0.5257020914453097
