Illumina Casava1.7 software used for basecalling.
Reads mapped to hg18 using bowtie 0.12.7, with -m 1 allowing one location per read
Mapped reads filtered to allow one read per position
Pol II and p300 binding sites calculated using MACS 1.4.1, -s hg, --p-value=1e-8
H2AZ analyzed with SICER using -w 200 -g 400 -t 0.68 -e 100 -f 150 -p 1e-5
H3K4 analyzed with SICER using -w 200 -g 200 -t 0.68 -e 100 -f 150 -p 1e-5
Brg1 analyzed with SICER using -w 200 -g 600 -t 0.68 -e 100 -f 150 -p 1e-5
H3K27 analyzed with SICER using predicted -w -I 150 -t 0.68 -e 100 -g 0 -f 150 -p 1e-5,
Outermost windows of H3K27 islands were trimmed to maximize the difference between island and non-island bins of 50bp
Genome_build: hg18
Supplementary_files_format_and_content: BED: chromosome, start, end, ReadID, number of mapping locations of read, strand
