si_find_bursts: Find bursts

In meaRtools: Micro-Electro Array (MEA) Analysis

Description

For one spike train, find the bursts using the Poisson surprise method.

Usage

si_find_bursts(spikes,s_min,burst_isi_max)

Arguments

spikes	A spike train of one channel, located in MEA data structure (example S$spikes[[1]]).
s_min	A minimum value for the surprise index
burst_isi_max	ISI threshold used by the the surprise index algorithm

Value

Returns a matrix of burst information for a specific channel. Matrix columns are:

beg	the number of spike that is first in the burst
end	number of the last spike in the burst
ibi	time interval from previous burst
durn	durarion of burst in seconds
mean_isis	average inter spike interval within the burst
si	surprise index
