0.4.0

Neuropixels-PXI Plugin v0.4.0

Release Notes

• Update code for compatibility with APIv8
• Upgrade to Neuropixels API v3.42
• Add support for switchable Neuropixels Ultra probes
• Change default probe naming scheme to "ProbeA", "ProbeB", etc., instead of using subprocessor-based numeric indexing
• Add new user interface for naming probes based on port or serial number
• Include metadata about probe ADC count in settings -- used by Neuropixels CAR plugin
• Remove option to select internal references (only tip and ext can be used)
• Improve rendering of probe activity view
• Add pop-up menu for selecting different probe types in simulation mode
• Add ability to update probe settings (selected electrodes, gain, and reference) and retrieve info about connected probes via the Open Ephys HTTP server
• Add offset correction for 1.0 probes -- signals are now centered around zero
• Store previously used IMRO files to allow quick loading
• Improve efficiency of data streaming, reducing overall CPU load

0.3.4

Neuropixels-PXI Plugin v0.3.4

Release Notes

• Add SimulatedProbe produces synthetic spikes and events for signal chain testing.
• Add SimulatedProbe generates LFP stream only if the probe version supports it.
• Fix uninitialized variable to correctly include the sync line as a continuous channel
• Fix loading IMRO settings for NHP probes.
• Fix LFPViewer pausing when NeuropixInterface is showing.

0.3.3

Neuropixels-PXI Plugin v0.3.3

Release Notes

• Add depth information to each channel. If electrodes other than the 384 channels at the tip are selected, the channels can now be sorted by depth in the LFP Viewer. For multi-shank Neuropixels 2.0 probes, channels are first grouped by shank, then sorted by depth.

• Add an online visualization of electrode peak-to-peak amplitude inside each probe's settings interface (update rate = 10 Hz). For probes that send both AP and LFP data, the amplitudes for either band can be viewed.

• Add the ability to export the current electrode layout in ProbeInterface JSON format. These files can be loaded by the ProbeInterface library in order to specify the channel map used for spike sorting.

• Electrode X/Y locations are now stored in the settings.xml configuration file.

• Display a warning in the console with the timestamp at which dropped samples occurred. This should only happen if the PXI buffer overflows, which was previously indicated by the yellow buffer monitor reaching 100%. Now, the precise timestamp at which this overflow occurred will be logged.

0.3.2

• Fix electrode selection on basestations running older v1 firmware.
• Prevent version mismatch error when v3 basestation has no probes connected.
• Explicitly distinguish v1 and v3 basestations by firmware version.

0.3.1

• Correctly configure SMA output for basestations running v1 firmware
• Turn off SMA output before closing basestations running v3 firmware

0.3.0

• Restore probe settings after running built-in self tests, as both “signal” and “noise” tests change AP and LFP band gain
• When adding sync as a continuous channel (385), include it in the LFP data stream, and fix the bug when loading the saved configuration
• Add more verbose console output, using a thread-safe logger
