SpyKING CIRCUS 2: tuning

Names on this page

Names in code font are fields of the sorter’s Rust configuration; --show-config prints them all with their values. The ones dspk sort accepts as flags are on the settings page. The rest are reachable from Rust only, for now.

Setting	Raise it	Lower it
detect_threshold (5)	fewer, larger peaks to cluster	more small units, more noise peaks
min_cluster_size (20)	fewer, larger clusters	more small clusters (also slower)
merge_similarity (0.8)	fewer merges: units split across templates stay split	more merges: similar units joined
min_snr (5)	only large templates are matched	small units kept (more false ones)
omp_min_amplitude (0.6)	only spikes close to their template’s size	more small matches (and noise)
n_peaks_per_channel (5000)	more peaks clustered: rare units found, slower	faster, rare units missed

Check a change with the unit labels and composite score of the sorting (to_sorting_output), and against another sorter on the same recording (Benchmarks).
