Release notes |
|
- Info window, viewable across the lab - with speech output, if you cannot spare a glance

Updates |
|
- Sampling supports Talker specification v5, which has more efficient data transfers
- New file importer added for XDF files (LabRecorder, LabStreamingLayer - LSL)
- Online Measure to channel command can send output to the Keyboard marker channel that can trigger writing to disk, the output sequencer and arbitrary waveform output
- New virtual channel function TEvt() to generate a ramp of time since the last event on a channel. This can be scaled to produce a calculation of the volume of liquid delivered by an automatic syringe, for example
- In the Sampling Configuration, you can apply a real-time channel Process (for example filter or rectify) to a Talker-based Waveform or RealWave channels
- The Sampling Configuration has a new Script tab to set a script to run at preset times during sampling
- New Linear Predict... command will replace short artifacts in Time view waveform data and Result view channels with estimations based on the previous and following data
- The Sampling configuration dialog Mode tab has a new option to control the s2video application Slow frame rate when not writing data to disk
- The output sequencer can now play trains of digital pulses at the same time as other sequencer operations
- There is a new Time view drawing mode, Interval, that displays the intervals between events
- There is a new data file importer for ADInstrument Labchart files
- You can change the output channel labels in the Graphical Sequence Editor
- The Sampling Configuration - Mode tab can now set scripts that are run when a trigger event is detected

| Version 9 |
06/2017 |
Release notes |
|
- Talkers can work without a 1401 interface
- Channel numbers extended to 2000
- Rows in grid views increased to 1,000,000
- Memory blocks for waveform output increased to 62 for Powers, to 20 for Micros
- New numeric operators for the script language
- More dialogs are resizeable

Updates |
|
- The s2video application now uses .mp4 files with improved frame timing and connects to a wider range of video sources.
- Spike2 multimedia support reads both .mp4 and .avi files.
- Added the mp4comp application for off-line compression of .mp4 video files.
- The Bionic and Ripple importers were revised to cope with importing huge (more than 500 GB) files. The importers now run at about the same speed as copying the files (15 minutes for 500 GB rather than a day).
- A Talker licence system is implemented. This allows us to update paid-for Talkers from our web site, but requires users to apply a licence key to their copy of Spike2. Talker licences are tied to the Spike2 serial number.
- There is a new event Frequency histogram analysis. This is similar to the Interval Histogram, but it places data in bins based on frequency, not intervals. The script language equivalent of this command is SetFHst().
- Channel Process is extended to allow time shifts of event channels and debounce of event and Level event channels.
- The ArrCWT() script command calculates the Continuous Wavelet Transform of an array of data.
