Analysis of VWG and other tri-nucleotide motif sets for chromosome 1.

V = A/C/G, W = A/T, S = C/G, H = A/T/C, M = A/C, R = A/G; Each motif set included the complements, giving 10 to 12 motifs per set. VWG and non-VWG motifs are listed. aAverage fraction of 100 kb windows that contain signals throughout the chromosome. bP-value for the degree of concordance between VWG signals and other motif signals throughout the chromosome. cAverage fraction of 100 kb windows that contain signals in RCS (<0.5 cM/Mb). dP-value for the significance of the difference between the signals/window in RCSs and on the whole chromosome.
