NeuropixelsV1DataFrame

Buffered data from a NeuropixelsV1 probe.

Properties

Property	Type	Description
FrameCount	int[]	Gets the frame count value array. A 20-bit counter on the probe that increments its value for every "frame" produced by the probe. Thirteen frames are produced for each 384-channel column of samples in SpikeData. The value ranges from 0 to 1048575 (2^20-1), and should always increment by 1 until it wraps around back to 0. This can be used to detect dropped frames.
LfpData	Mat	Gets LFP-band electrophysiology data array. LFP-band (0.5-500 Hz) samples are organized in 384xN matrix with rows representing channel number and N columns representing samples acquired at 2.5 kHz. Each column is a 384-channel vector of ADC samples whose acquisition time is indicated by the corresponding elements in Clock and HubClock. Each ADC sample is a 10-bit, offset binary value represented as a ushort. The following equation can be used to convert a sample to microvolts: Electrode Voltage (µV) = (1,171.875 / LFP Gain) × (ADC Sample – 512) where LFP Gain can be 50, 125, 250, 500, 1000, 1500, 2000, or 3000 depending on the value of LfpAmplifierGain.
SpikeData	Mat	Gets spike-band electrophysiology data array. Spike-band (0.3-10 kHz) samples are organized in 384xN matrix with rows representing channel number and N columns representing samples acquired at 30 kHz. Each column is a 384-channel vector of ADC samples whose acquisition time is indicated by the corresponding elements in Clock and HubClock. Each ADC sample is a 10-bit, offset binary value represented as a ushort. The following equation can be used to convert a sample to microvolts: Electrode Voltage (µV) = (1,171.875 / AP Gain) × (ADC Sample – 512) where AP Gain can be 50, 125, 250, 500, 1000, 1500, 2000, or 3000 depending on the value of SpikeAmplifierGain.
Clock	ulong[]	Gets the buffered array of Clock values.
HubClock	ulong[]	Gets the buffered array of HubClock values.
