New Software and Tutorial: Generalized Multiscale Entropy (GMSE)

GMSE is a new computational tool for quantifying the volatility of time series. This work extends the multiscale entropy (MSE) algorithm currently available on PhysioNet. The GMSE method was first described in Costa M., Goldberger A.L. Generalized Multiscale Entropy Analysis: Application to Quantifying the Complex Volatility of Human Heartbeat Time Series. Entropy 2015;17:1197-1203.

New Platform In Alpha Testing

The PhysioNet team has been working on its new web platform. The site is being alpha tested here at https://alpha.physionet.org/. The original site will continue running at https://physionet.org/ until its content and functionality is ported over.

You can leave feedback and track our progress via the development repository.
