Table 2 Correlation coefficients between D, PS and OUV of n0_4 mer local patterns with those of the corresponding n1, n2 and n3 normalized patterns

Parameters	Normalization type
	n1_4 mer	n2_4 mer	n3_4 mer
plasmid pKLC102, window 5,000 bp, step 2,500 bp
D:n0_4 mer	0.85*	0.82	0.40
PS:n0_4 mer	0.40	0.60	0.10
OUV:n0_4 mer	0.89	0.83	0.39
1 Mbp-2 Mbp locus of E. coli K12 chromosome, window 10,000 bp, step 5,000 bp
D:n0_4 mer	0.94	0.84	0.63
PS:n0_4 mer	0.88	0.75	0.53
OUV:n0_4 mer	0.61	0.46	0.35

*Values in the cells of the table indicate the correlation coefficients between respective OU statistical parameters D, PS and OUV determined for n0 patterns and the normalized patterns n1, n2 and n3. For example, 0.85 is the correlation coefficient between series of values D:n0_4 mer and D:n1_4 mer determined for overlapping 5 kbp fragments of pKLC102.
