Rasters

The raster display shows the spikes as vertical lines (tick) positioned according to the spikes timestamps. For continuous variables, the raster display shows signal versus time graph. This analysis does not generate numerical results since the raster lines are drawn directly from the data.

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. For continuous variables, the raster display shows signal versus time graph.
