Data downloaded from GEO (GSE30202) for ES cell and NP cell
The sga files were gerenerated from tab-delimited text files available from the URL indicated above. These files provide the total number of read and non-methylated reads that map to C-residues in the mouse genome assembly mm9. Two sga files were generated from each experiment providing the coordinates of "methylated" and "demethylated" (methylation-depleted) C residues, respectively. Only C-residues that occur in a CpG context were considered. A C-residues was considered "methylated" if at least 50% of the reads covering the residue indicated methylation.
