Raster Plot
The Raster Plot screen displays spikes as a pixelized image, each pixel representing a signal impulse sampled for the
length of time set by the user in the drop-down box. In this example, 50 pix/sec indicates that each second of data is
represented by 50 pixels on the screen. Continuous analog data can also be shown.

o Play: When selected, Raster Plot displays wrap.
o Scroll: When selected, Raster Plot displays scrolls.
o Pause: When selected, the Raster Plot display will pause.
o One Line per Channel: When selected, all spike events on a channel will be displayed on one line.
o Split Channel: Splits single channels in the raster plot display. A channel can be displayed by online classification rules
and continuous waveforms.
o Rate: Lets the user select the scrolling speed at which the raster plot displays the data. Set the range from 4 pix/sec to
100 pix/sec (pixels per seconds).
o Decrease size, Increase size, Minimize, and Maximize Channels: Select a channel (or group of channels) in the raster
plot to increase or decrease the size of the selected channels.
o Delete Channel: Click this button after selecting a channel or group of channels to delete them from the raster plot
display.
o Move Down, Move Up: Use these buttons to move one or a group of channels up or down in order on the raster plot
display.
o Scale Continuous Data: Use this button to display continuous waveform in the raster plot module and adjust the scale
for display.
o Refresh: Refreshes the raster plot display.
o Sort: This button sorts the channels in the raster plot display. Click the drop down arrow to display the sorting types
then select sort by Channel ID, Recording Mode, or Unit ID.
o Choose Channels, Add All, Clear All: Click the Choose Channels button to select a group of channels to add or remove
from the raster plot display. To add all channels to the display, click the Add All button. The Clear All button will
remove all channels from the raster display.
o Open Selected Channels: After selecting a channel or group of channels to display in Neural Channel, click this button
to open the selected channels.
