ADA – Actigraphic Data Analyzer

ADA stands for Actigraphic Data Analyzer, coincidentally being also the name of the first programmer in the world. It is an open source Python module for processing, analyzing and visualizing actigraphic data, with the main focus on bedtime sleep/wake classification and circadian rhythms analysis. ADA is usable in the form of a python package, and in the form of a standalone application with graphical interface (GUI).

Installation

Python 3.11 or higher is required. To install the Python package use pip:

pip install acti-data-analyzer

GUI version of ADA can be installed and run on any system as a Python script, best within a venv. To do use following commands:

pip install 'acti-data-analyzer[gui]'
python -m ada_gui

The GUI for Windows 10 and Windows 11 is available also as a standalone executable. It can be downloaded from the Releases tab, available also under the link, as an ADA.exe file.

Main features

• Reading and writing data from:
  • GENEActiv .bin and .csv files
  • Actigraph Corp .gt3x and .csv files
  • The MESA dataset.
• Converting data to native .ada format (much more efficient in terms of disk space and reading speed).
• Multiple algorithms allowing collapsing into epochs:
  • MIMS
  • ActivityIndex
  • ENMO
  • Resampling
• Sleep/wake scoring using multiple algorithms:
  • Cole-Kripke
  • Webster
  • Scripps Clinic
  • UCSD
  • Sazonov
  • Unified Filter, with possibility of custom filter construction.
• Estimating multiple sleep metrics:
  • Sleep efficiency
  • Sleep fragmentation index
  • Sleep onset latency
  • Wake after sleep onset
  • And more.
• Assessing circadian rhythms:
  • Single and multi-component cosinor in linear and nonlinear variants
  • Sigmoidally-transformed cosinor
  • Spectrum estimator using autoregressive model
  • Detrended Fluctuation Analysis
  • Nonparametric measures: Interdaily Stability, Intradaily Variability, M10, L5.
• Easy to read and analyze summaries of sleep/wake and circadian assessments for multiple subjects (in a form of comma-separated CSV).
• Automatic and customizable synchronization of actigraphic data with PSG staging.
• Plotting of all analysis steps.
