Similarities between cyclic hydrocarbon-evoked patterns and other patterns¹

	Most closely correlated odorant-evoked patterns
Odorant	#1	#2	#3	#4	Highest r	Heptane r
Cyclooctane	2-Octyne	Heptane	Ethylbenzene	1,7-Octadiene	0.63	0.62
Cycloheptane	Heptane	2-Octyne	2-Hexanone	Ethylbenzene	0.71	0.71
Cyclohexane	2-Octyne	cis-4-Octene	Heptane	trans-2-Octene	0.58	0.56
Methylcyclohexane	Ethylbenzene	Butyl propionate	trans-4-Octene	Butyl acetate	0.57	0.51

¹The activity pattern evoked by each alicyclic hydrocarbon at 1000 ppm was compared to all other previously published evoked patterns in our database at the time of writing (264 patterns representing 184 unique odorants) by way of pair-wise cell-by-cell correlation analyses of the underlying data matrices. Shown here are the odorants associated with the highest Pearson correlation coefficients (r). Also listed for each odorant is the correlation coefficient describing the similarity in pattern between the odorant and the odorant listed as #1, as well as the correlation coefficient for each odorant compared to heptane.
