Single linkage dendrograms showing clustering of persistence barcodes obtained from 15 pairs of parameter choices.

The x-axis corresponds to bottleneck distance. The y-axis corresponds to labels of the arenas. 0-4 hole arenas correspond to blue, green, red, magenta, and orange lines, respectively. Top, middle, and bottom rows correspond to fixed place field sizes of 14 cm, 15 cm, and 16 cm, respectively. From left to right, the columns correspond to fixed firing rates of 12 Hz, 14 Hz, 16 Hz, 18 Hz, and 20 Hz, respectively. See the discussion on the effect of parameters on error rates in §Results and §Materials and methods.
