2.14. Rasters

The raster display shows the spikes as vertical lines (tick) positioned according to the spikes

timestamps. This analysis does not generate numerical results since the raster lines (ticks) are drawn

directly from the data. Some generic analysis statistics are available in the Summary of Numerical

Results (see below).

Parameters

Parameter Description

XMin Time axis minimum in seconds.

XMax Time axis maximum in seconds

Select Data If Select Data is From Time Range, only the data from the specified (by

Select Data From and Select Data To parameters) time range will be used

in analysis. See also Data Selection Options.

Select Data From Start of the time range in seconds.

Select Data To End of the time range in seconds.

Interval filter Specifies the interval filter(s) that will be used to preselect data before

analysis. See also Data Selection Options.

Vert. size The size of a raster tick (in percent of the graph height).

Summary of Numerical Results

The following information is available in the Summary of Numerical Results

Column Description

Variable Variable name.

YMin Y axis minimum (added for compatibility with other analyses, always 0).

YMax Y axis maximum (added for compatibility with other analyses, always 1).

Spikes The number of spikes used in calculation.

Filter Length The length of all the intervals of the interval filter (if a filter was used) or the

length or the recording session (in seconds).

Mean Freq. Mean firing rate (Spikes/Filter_Length).

Algorithm

The raster display shows the spikes as vertical lines positioned according to the spikes timestamps.
