A4Precise Events

Module name: A4PreciseEvents

Package: CEAMSModules 7.4.0

Version: 2.0.0

Overview

Precise the A4 spindle events.

Inputs

Input

Format

Default

Description

signals

a list of SignalModel

signal.samples : The actual signal data as numpy list
signal.sample_rate : sampling rate of the signal (used to STFT)
signal.channel : current channel label

events

Pandas DataFrame

DataFrame events (columns=[‘group’,’name’,’start_sec’,’duration_sec’,’channels’])
A4 Events detected with a windows length and windows step = 0.25 sec

threshold_events

list of float

A threshold value for each event nammed “event_name” from this current detector

win_len_sec

Float

0.25

The window length in seconds used to compute the RMS value.

len_adjust_sec

Float

0.5

The window length in seconds to evaluate before and after each event in order to precise the event.

min_len_sec

float

0

The accepted minimum length in sec (any spindle shorter are discarded)

max_len_sec

float

5

The accepted maximum length in sec (any spindle longer are discarded)

event_group

string

The event group to limit the length and precise the onset and duration.
All the events are selected when event_group is empty.

event_name

string

The event name to limit the length and precise the onset and duration.
All the events are selected when event_name is empty.

Outputs

Output

Format

Description

events

Pandas DataFrame

DataFrame events (columns=[‘group’,’name’,’start_sec’,’duration_sec’,’channels’])
New events with precise onset and duration.

Usage in a process

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

  2. In the Module Library, find A4Precise Events under the Detectors 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.
