README

Processed cytosine methylation maps of all samples in Zeng et al. (2012) are recorded in two different contexts, namely CpG and non-CpG contexts.

The compressed file "jzeng6_nonCG_methylation.tar.gz" records methylation at non-CpG context. It contain 6 files for each sample in this study, which are HS1570_methylation_nonCG.gff, HS1832_methylation_nonCG.gff, HS813_methylation_nonCG.gff, Y0404_methylation_nonCG.gff, Y0430_methylation_nonCG.gff and Y06147_methylation_nonCG.gff.

The compressed file "jzeng6_CG_methylation.tar.gz" records methylation at CpG context. It contain 6 files for each sample in this study, which are HS1570_methylation_CG.gff, HS1832_methylation_CG.gff, HS813_methylation_CG.gff, Y0404_methylation_CG.gff, Y0430_methylation_CG.gff and Y06147_methylation_CG.gff.

All files have 9 columns which are based on the GFF (General Feature Format) standard file format. For more information on the GFF format, please refer to http://www.sanger.ac.uk/resources/software/gff/.
