sttcp: Compute

In meaRtools: Micro-Electro Array (MEA) Analysis

Description

Compute STTC profile for a pair of spike trains

Usage

sttcp(a, b, dt = 0.05, tau_max = 5, tau_step = 0.1, beg = NULL,
  end = NULL)

Arguments

a	spike train 1
b	spike train 2
dt	time window for STTC
tau_max	maximum time shift
tau_step	step size in tau
beg	start of recording. When NULL use the minimum spike time from the two trains.
end	end of recording. When NULL use the maximum spike time from the two trains.

Details

We extend the STTC to a profile (or correlogram) by shifting one spike train by amount tau, where tau varies in [-tau_max, +tau_max] in steps of tau_step.

Value

List containing the STTC profile.

Examples

t1 <- -cumsum(log(runif(1000)) / 2)
t2 <- -cumsum(log(runif(1000)) / 2)
corr <- sttcp(t1, t2)
plot(corr, main="cross correlation")
autocorr <- sttcp(t1, t1)
plot(autocorr, main="auto correlation")
