Spike Toolbox

STISIHist
Construct an ISI histogram for a spike train

Syntax
[vISIHist, tTimeBins] = STISIHist(stTrain <, bUseLog, nNumBins>) [vISIHist, tTimeBins] = STISIHist(stTrain <, bUseLog, tTimeBins>) [mISIHist, tTimeBins] = STISIHist(cellstTrain, ...)

Description
STISIHist will calculate an ISI histogram for the spike train stTrain. vISIHist will be the count in each histogram bin, for the bin centres specified in tTimeBins. vISIHist and tTimeBins will be vectors of the same length.

The optional argument bUseLog can be used to specify a log time scale for calcualting the histogram. The default is to use a linear time scale. The optional argument nNumBins can be used to specify the number of histogram bins to use. The default is 50 bins.

If a vector is supplied for tTimeBins, the specified time bins will be used instead. tTimeBins should be a vector of bin centres.

If a cell array is supplied for cellstTrain, then histogramming will be performed for each of the supplied trains. In this case, the identical time bins will be used for each histogram. mISIHist will be a matrix, with the histogram for each train along the rows of the matrix.

If no output arguments are supplied, STISIHist will construct a plot of the ISI histogram.
