Extended Data Fig. 6: Comparison to the EMD method.

a, We tested the performance of the EMD algorithm and UnitMatch on matching neurons from two halves of the same session in five mice. Note that this is a proportion relative to Kilosort output, and a small fraction of units from Kilosort should potentially have been merged. b, We compared matching performance in 22 recordings of example mouse 1. Since inter-spike-interval (ISI) histograms are generally stable (Fig. 4), we used the area under the curve (AUC) of ISI correlations to validate the pairs found by both algorithms. AUC values were significantly (***, paired t-test; t(20)=4.57, p=0.0002) larger for UnitMatch than for the EMD algorithm.
