Data processing |
Illumina Casava software 1.8.2 used for basecalling of Hiseq2000 and NextSeq 500 data. Library strategy: ChIP-seq. The reads were aligned to build version mm9 of the mouse genome using bwa (version 0.7.12) with default parameters. Only uniquely mapped reads were kept for downstream analysis. Reads from PCR duplicates were also removed. MACS (version 2.0.10.20130306), was used to identify regions of ChIP-seq enrichment over background using parameters --nomodel --broad. Library strategy: RNA-seq. MMSEQ package was used to infer gene expression levels. Reads were mapped to mouse gene annotation (Ensemble release 67). Library strategy: Capture Hi-C. The two ends of paired-end reads were mapped to the reference mouse genome (mm9) separately, using BWA MEM (version 0.7.12) with default parameters. Reads were filtered based on mapping quality score (both ends mapQ ≥ 10) and PCR duplicates were removed. Reads were removed if the two ends are from the same DpnII fragment. CHICAGO CHi-C analysis package (http://regulatorygenomicsgroup.org/chicago) was used to call significant contacts. To increase quality, the whole genome was windowed into 5 DpnII site tiles. Virtual baits were created by merging adjacent target regions. Interactions were filtered based on interaction score and number of reads (score ≥ 5 and at least 5 reads). Library strategy: DNaseI-seq. The reads were aligned to build version mm9 of the mouse genome using bwa (version 0.7.12) with default parameters. Only uniquely mapped reads were kept for downstream analysis. Reads from PCR duplicates were also removed. MACS (version 2.0.10.20130306), was used to identify DNaseI hyper-sensitive sites using parameters --nomodel --broad. Library strategy: 4C-seq. The initial step in the 4C-seq analysis is the alignment of the sequencing reads to a reduced genome of sequences that flank HindIII sites (fragment ends). Repetitive fragment ends were excluded from subsequent analysis. The reduced genome was based on mouse genome mm9. Genome_build: mm9
