genomic DNA |
| Extraction protocol |
Genomic DNA was extracted with the AllPrep DNA/RNA Mini Kit (Qiagen).
RRBS libraries were prepared as described in Auclair et al., Genome Biol 15:545 (2014). Briefly, we digested genomic DNA 5 hours with MspI (ThermoFisher Scientific), followed by end-repair and A-tailing with 5 U Klenow-fragment exo- (ThermoFisher Scientific) and ligation to methylated adapters overnight at 16°C with 30 U T4 DNA ligase (ThermoFisher Scientific) in Tango 1X buffer. Fragments between 150 and 400 bp were excised from a 3% agarose 0.5X TBE gel with the MinElute kit (Qiagen) and bisulfite-converted with the EpiTect Bisulfite kit (Qiagen) using two consecutive rounds of conversion. Final RRBS libraries were amplified with 14-16 cycles of PCR. The libraries were purified using Ampure XP beads (Beckman Coulter).

| Data processing |
Reads were cleaned with Trim Galore v0.4.2 using the parameters --rrbs --paired -r1 30 -r2 30 -q 20 --length 20 --stringency 5 --retain_unpaired. Reads were aligned to the mouse mm10 genome with BSMAP v2.74 using the parameters -v 2 -w 100 -r 1 -x 400 -m 30 -D C-CGG -n 1. Methylation percent values were extracted with methratio.py from BSMAP v2.74 using the parameters -z -u -g. CGs were filtered to have a minimum sequencing depth of 8X using custom developped scripts in R.
Genome_build: mm10
Supplementary_files_format_and_content: IGV files containing methylation scores for all CGs with at least 8X sequencing depth.
