Spike2 records waveform, time-stamp and marker data. Waveform channels can be captured at different sampling rates, with synchronising stimulus and pacing pulses logged as time-stamp data to the same file. Text comments placed in the record during data sampling are easily located for review and analysis of experiment stages.
Active cursors search for features in waveform data and latch to time-stamps. You can also position cursors with "expressions", such as , Cursor (1) +5 to force a second cursor five seconds in advance of the first for comparative area measurements.
The CED 1401 interface generates pacing pulses and stimulus amplitude values via Spike2's built-in sequencer. A graphical editor with drag-and-drop interaction allows fast and easy creation of stimulus protocols. For more complex output and control requirements, a text editor enables direct access to the sequencer code. Further on-line control of the outputs is available through script interaction.
Spike2 can perform on-line and off-line detection of waveform features and mark these in a new channel in the data file using the built-in active cursor and measurement functions. This video tutorial shows how to generate heart rate from a blood pressure trace.
