stim

This module contains functions for extracting stimulus timing from signals sent to SLAP2

Functions

slap2_utils.functions.stim.returnStimTime(stimFile, distance=250, hz=5000)

Return start and stop times of visual stimuli from a TTL trace.

This function reads a TTL trace from an HDF5 file and identifies the start and stop times of visual stimuli based on peaks in the trace.

Parameters:

  • stimFile (str) – Path to the HDF5 file containing the TTL trace.

  • distance (int, optional) – Minimum number of samples between consecutive peaks. Default is 250.

  • hz (int, optional) – Sampling rate of the TTL trace in Hertz. Default is 5000 Hz.

Returns:

  • start (list of float) – List of start times of the visual stimuli in seconds.

  • stop (list of float) – List of stop times of the visual stimuli in seconds.
