The FeatureFinder program can be used to view your data in various forms, and also to extract important features, such as the amplitude of an electromyogram (EMG) signal in a specific region or the heart rate of a photoplethysmogram (PPG) signal. Once a profile has been setup, you can preview the effects of different processing and feature settings, e.g., filter type and target window length, on any data file associated with your profile. You can then extract your features into a text file for easy input into a spreadsheet or statistics program.
