| Extraction protocol |
Lysates were clarified from sonicated nuclei and histone-DNA complexes were isolated with antibody. After end-repair and addition of an ‘A’ base to the 3’ ends, the adapters were ligated to the ends of the DNA Fragments using 2 µl of fourtyfold diluted ‘Adapter oligo mix’ in a total reaction volume of 25 µl. Between these steps, the DNA was purified using the DNA Clean-and-Concentrator-5 kit (Zymo Research). Subsequently, the DNA was amplified by 18 cycles of PCR, purified with MinElute PCR Purification Kit, and eluted with 32 µl of 10 mM tris buffer at pH8.5. The PCR-product was sized fractionated on 2% agarose gel and a gel slice containing the 200-300 bp fragments was excised. The purified DNA was captured on an Illumina flow cell for cluster generation. Libraries were sequenced on the Genome Analyzer following the manufacturer's protocols.

| Data processing |
Basecalls performed using CASAVA version 1.7
ChIP-seq reads were aligned to the hg18 genome assembly using bwa 0.6.1 with the default parameters
BAM files were filtered and all reads with quality score below 15 are skipped, then the resulting BAM is filtered using the UCSC Duke excluded regions for hg18
Rseg differential was used to identify significant domains in the data using mode 2 versus input
Genome_build: NCBI Build 36.1 (HG18)
Supplementary_files_format_and_content: UCSC bed format of significant regions identified by Rseg
