detectSpikesFromTrace: Detect spikes times in a filtered signal.

In kevin-allen/relectro: Analysis of electrophysiological data

Description

This function works on the data of a single channel. It calculates the power with the function powerRootMeanSquare(), and calculates the mean and standard deviation. It calls identifySpikeTimes() to get the spike times and other parameters of the detected spikes.

Usage

detectSpikesFromTrace(data, samplingRate, powerWindowSizeMs, powerWindowSlideMs,
  SDThreshold, spikeDetectionRefractoryMs)

Arguments

data	Vector containing the spikes and some noise
samplingRate	Sampling rate of the trace
powerWindowSizeMs	Window size when calculating power (root mean square)
powerWindowSlideMs	Shift of the window in ms between estimation of power
SDThreshold	Power threshold for spike detection.
spikeDetectionRefractoryMs	Refractory period in the spike detection

Details

If there are low frequency components in the signal, they should be filtered out.

Value

list containing rms, rmsT, rmsSD, rmsMean, rmsThreshold, spikeTime, spikePower, spikeTrough
