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.
