Signal Stats

Module name: SignalStats

Package: CEAMSModules 7.4.0

Version: 2.0.0

Overview

Compute the mean and standard deviation of the input signals per epoch, per channel.

Note

For each epoch (each item in the SignalModel list), the module calculates the mean and standard deviation. The module accepts NaN values in the signals and will ignore them in the calculations.

Inputs

Input	Format	Default	Description
signals	List of SignalModel	—	List of signal with dictionary of channels with SignalModel with properties : name: The name of the channel samples: The samples of the signal alias: The alias of the channel sample_rate: The sample rate of the signal start_time: The start time of the recording montage_index: The index of the montage used for this signal is_modified: Value characterizing if the signal has been modified from the original

Outputs

Output	Format	Description
stats	dict	A dictionary containing statistical properties of the signals. - ‘mean’: List of mean values computed from the input signals. - ‘std’: List of standard deviation values computed from the input signals.

Usage in a process

1. Open Dev Tools -> New process in Snooz.

2. In the Module Library, find Signal Stats under the Statistics category.

3. Drag the module onto the process canvas.

4. Connect the required inputs from upstream modules (or set values in the Settings tab).

5. Connect outputs to downstream modules as needed.

6. Double-click the module to configure parameters in the Settings tab.

7. Run the process and inspect results in the Results tab.
