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
.
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
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.
