Summary statistics for the CGI densities for each chromosome.

Column 1: Chromosome. Column 2: Length in Mb (including missing sequence that was not assayed). Column 3: Ambiguous or missing sequence in Mb not assayed. Column 4: Number of CGI detected. Column 5*: Density = NCpG/(Total Mb – missing Mb not assayed). Column 6:* Mean number CGI per Mb for entire chromosome. Column 7: Standard deviation of number of CGI per Mb for entire chromosome. Column 8: Skewness of number of CGI per Mb.for entire chromosome. *The density is simply computed as the total number of CGI/chromosome length in Mb that have been assayed. This is formally not the same as the mean number of CGI per Mb of chromosome ignoring the missing Mb, which we compute by counting CGI in windows of 1 Mb and computing the mean, standard deviation and skewness of the resulting distribution.
