Figure 2. Characteristics of the BOPs belonging to different probe classes.

(A) Numbers of BOPs and CpG probes in Class A, Class B and Class C. For Class A and Class B, subdivision in CpG islands, N-Shores, S-Shores, N-Shelves and S-Shelves is reported. In the lower part of the tables, descriptive statistics for the distribution of number of probes/BOP in the 3 Classes are reported. (B) Descriptive statistics for the distribution of mean bp distance between probes /BOP in the 3 Classes are reported.(C) Density distributions (upper panel) and frequency histograms (lower panels) of the mean bp distance between the probes/BOP.
