detect_threshold

[Alkohost]

Hello, I have have some questions about detect_threshold parameter. When I use detect_threshold=15, I get 3 clear clusters (15 is seems a lot, no?). When I change this parameter in range of [1 10] I get usually only 1 cluster with weak-changing number of spikes detected, whereas I wait at least 3 evident output clusters.

I use only adjacency_radius and detect_threshold as a specified input parameters. What should I do to get the optimal results and how the detect_threshold should affect to number of clusters and number of spikes in a cluster?
