NeuropixelsV2eBetaDataFrame

Buffered data from a NeuropixelsV2-Beta probe.

Properties

Property Type Description
AmplifierData Mat

Gets the buffered electrophysiology data array.

Electrophysiology samples are organized in 384xN matrix with rows representing electrophysiology 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 14-bit, offset binary value represented as a ushort. The following equation can be used to convert a sample to microvolts:

Electrode Voltage (µV) = 0.76294 × (ADC Sample – 8192)
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. Sixteen frames are produced for each 384-channel column of samples in AmplifierData. 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.

Clock ulong[]

Gets the buffered array of Clock values.

HubClock ulong[]

Gets the buffered array of HubClock values.
