Spike2 laboratory software delivers powerful data capture and analysis, stimulus sequencing and experimental control using one of the CED family of data acquisition peripherals. Specifically developed for life science research, Spike2 is already used in hundreds of laboratories world-wide for a diverse range of applications. Version 3 is the latest release of this versatile tool. Spike2 records up to 19 channels as a combination of waveform, event, digital marker, notepad, keyboard marker and templated spikes. Different waveform channels can be sampled to disk continuously at independent frequencies up to an aggregate rate of 166kHz.

Spike2 has menu functions for fast manipulation of data and drawing modes as well as analysis for event processing, including INTH, PSTH and event correlations. Waveform analysis includes averaging, spectral analysis, waveform discrimination and cursor measurement facilities for areas, mean and gradient. Export of data to industry standard text and graphic formats is supported.

	Spike overdraw mode to show superimposed unit shapes
	Real-time access to incoming data using new output sequencer commands
	New text editor with data capacity limited only by system memory
	Script orientated features include text editor split views, function find and bookmarks
	Faster script compile speed and script execution
	Script commands to support XY views, triggered display modes, system time and date
	Scaled Metafile output for easier import to drawing programs

Future Spike2 improvements
Future upgrades of Spike2 version 3 will be available free of charge as downloads from our Web site or alternatively by contacting CED directly. Future additions include built-in Finite Impulse Response filtering and output of arbitrary waveforms both on and off-line.

New script features
FFT waterfall drawn in an XY view and sonogram display	Eye-movement and pharmacological experiments benefit greatly from the new XY views. These views, controlled by the Spike2 script language, contain up to 256 channels of x,y data points drawn in a shared window. Channels are independent of each other and there is no limit to the number of data points each may have, except for available memory. Measurements of data points lying within areas and other common calculations are supported directly. XY views can be saved, printed and copied directly to the clipboard for use in other applications.
Context sensitive help and syntax colouring to highlight key words aid users in customising Spike2 for their own experiments. New editing features include split text views and bookmarks. Debugging and editing toolbars also make script generation faster. New Spike2 Time$()and Date$() commands can time stamp documents using the system clock. Output sequencer extensions enable the user to monitor input waveforms and events in real-time, and act on their condition.	Horizontal raster and PSTH

System requirements

Spike2 for Windows requires a CED Power1401, 1401plus, micro1401 or standard 1401 intelligent laboratory interface and an IBM compatible PC with Windows 95, 98, Me or NT 4, 2000 or XP. We recommend a minimum of 32MB of RAM is fitted.
