SpikePac Tech Notes
OpenEx threshold settings lost on mode change
Product: OpenEx, SpikePac
Date Added: 2016-01-29
OpenEx/SpikePac threshold settings are lost when changing from preview to record mode.
Instead of going directly from Preview to Record, change from Preview to Standby to Record. This gives Controller enough time to register the mode change and save/load the settings properly. This should keep your SpikePac threshold/sorting settings intact.
IZ2Stim Plot Display Requirements
Product: OpenEx, SpikePac, OpenController
Date Added: 2014-07-30
The IZ2Stim control included with SpikePac uses OpenGL 2.0 plotting. The version of OpenGL on the end user's computer must be version 2.0 or greater.
If a compatible version of the graphics driver isn't found when the IZ2StimGen control is run, the waveform diagram will appear empty and an error message is displayed in the plot area: Hardware acceleration not available. Please check the graphics card.
OpenGL is typically installed with windows as part of the graphics adapter driver and/or the graphics card driver. If the computer is using an outdated graphics driver, updating it should resolve the problem.
To update your video driver:
Open your Device Manager from the Windows Control Panel.
Right-click the graphics card or display adapter and click Update Driver Software on the short-cut menu.
Follow the onscreen instructions.
If updating the graphics driver does not resolve the problem, contact Support for assistance.
BoxSort not using all sorting windows
Product: OpenController, SpikePac, Synapse
Date Added: 2013-11-15
The BoxSort sorting algorithm does not work beyond 30 samples. Any boxes beyond the 30th sample in the waveform will not be used to classify the waveform during hardware sorting.
Make sure no boxes extend beyond the 30th sample or shorten your window width to 32 points. In v78 and above the maximum window width is 32 samples.
RPvdsEx update macro
Product: TDT Drivers, SpikePac, Synapse
Date Added: 2009-07-09
When an existing circuit is opened, RPvdsEx checks to see if any of the macros contained within the circuit are out-of-date by comparing the build date with the circuits last modified date. RPvdsEx will prompt a dialog that asks the user if they wish to update any out-of-date macros.
