cluster_spacetime_()

Run spatiotemporal Rodrguez-Laio clustering and determine the density (rho) and distance (delta) for each spike

Syntax

• S_clu = cluster_spacetime_(S0, P)
• S_clu = cluster_spacetime_(S0, P, vlRedo_spk)

Input

• S0: Master struct (S0)
• P: Parameters struct (P)
• vlRedo_spk: logical vector indicating spikes to be re-clustered (optinoal, default: [])

Output

• S_clu: Cluster struct (S_clu)

Operations

• For each site k
  • fet12_site_(): Collect features of the spikes whose peak (S0.viSite_spk) is at site k (n1 number of spikes), or whose second peak (S0.viSite2_spk) is at site k (n2 number of spikes).
  • Calculate the distance cutoff (dc), which is set at the Euclidean distance percentile (P.dc_percent)
  • cuda_rho_(): Calculate Rho (density) for n1 spikes
• For each site k
  • cuda_delta_(): Calculate delta (distance separation) for n1 spikes
