detect_spikes_()

Detect spikes from each site and group multiple detected spikes according to the spatiotemporal limits set by P.spkRefrac_ms and P.maxDist_site_um.

Syntax

• [viTime_spk, vrAmp_spk, viSite_spk] = detect_spikes_(mnWav3, vnThresh_site, vlKeep_ref, P)

Input

• mnWav3: filtered traces (nSamples_load x nSites: int16)
• vnThresh_site: Detection threshold for each site (nSites x 1: int16).
• vlKeep_ref: logical vector to enable spike detection (nSamples_load x 1: logical)
• P: Parameters struct (P)

Output

• viTime_spk: Spike times
• vrAmp_spk: Spike amplitudes
• viSite_spk: Spike sites

Operations

• spikeDetectSingle_fast_(): Perform spike detection for each channel using GPU
• spikeMerge_(): Merge spikes detected at multiple neighboring sites using multiple CPU cores
