simulateRawTrace: Generate raw traces with some background gaussian noise and...

In kevin-allen/relectro: Analysis of electrophysiological data

Description

Several different waveforms can be used. They are all generated from the same generic spike by adding gaussian noise to it.

Usage

simulateRawTrace(samplingRate = 20000, durationSec = 1, noiseSD = 100,
  noiseMean = 0, waveformAmplitude = 700, nClusters = 3, nChannels = 4,
  waveformDifferentiationSD = 200, minChannelScalling = 0.3,
  spikeJitterAcrossChannelMs = 0.1, maxSpikes = 10000)

Arguments

samplingRate	Sampling rate of the trace
durationSec	Total duration in second of the trace
noiseSD	Standard deviation of gaussian noise
noiseMean	Mean of noise
waveformAmplitude	Negative amplitude of the generic spike waveform
nClusters	Number of different waveforms (neurons) in the trace
nChannels	Number of channels, 4 in case of tetrodes
waveformDifferentiationSD	Differentiation of the waveforms of different cluster (gaussian noise added in generic waveform)
minChannelScalling	Minimal value (between 0 and 1) that can be used for creating the tetorde effect (scalling of waveform on different channels)
spikeJitterAcrossChannelMs	Time variation between the waveforms of a spike on the different channels.
maxSpikes	Maximum number of spikes to include in the traces

Value

list containing trace, spikeTimes and cluId
