What is Snooz?

The Snooz Toolbox is an open-access, open-source, custom-designed software platform for advanced PSG analysis.

It offers state-of-the-art, supervised automatic tools for artifact rejection, cohort harmonization, EEG spectral analysis, sleep bout identification, event detection (e.g., REM events, spindles, slow waves) and generation of sleep reports. The Snooz Toolbox is a multiplatform software compatible with Mac, Windows, and Linux and developed in Python, an object-oriented programming language.

Tools

Why using Snooz?

Snooz allows researchers and clinicians to process, analyze, and interpret complex sleep data in a more efficient and harmonized manner. Analyses can be performed by sleep stages and cycles, providing greater versatility in analytic approaches.

Support

A user-friendly platform

The platform is designed to be user-friendly, featuring two main interfaces:
1) for sleep experts, e.g., sleep technologists, physicians and trainees in clinical programs, with a step-by-step user interface requiring no programming skills and no use of command lines; and
2) for developers, including experts in signal processing, methodologists and engineers, with command lines for customizing and extending the software’s capabilities.
