The hierarchical clustering results were replicated 1,000 times, and the count of nearest odor pairs was tallied during these repetitions. The clustering count of the nearest odor pairs in the CV across the five frequency bands. A chi-square test was performed for this table. *p value<0.05, **p value<0.01, ***p value<0.001.
