| Data processing |
The 75-nt single-end (SE75 sequence reads generated by Illumina sequencing (using NextSeq 500) are mapped to the genome using the BWA algorithm (“bwa aln/samse” with default settings)
Only reads that pass Illumina’s purity filter, align with no more than 2 mismatches, and map uniquely to the genome are used in the subsequent analysis. In addition, duplicate reads (“PCR duplicates”) are removed.
Since the 5´-ends of the aligned reads (= “tags”) represent the end of ChIP/IP-fragments, the tags are extended in silico (using Active Motif software) at their 3´- ends to a length of 200 bp, which corresponds to the average fragment length in the size-selected library. To identify the density of fragments (extended tags) along the genome, the genome is divided into 32-nt bins and the number of fragments in each bin is determined. This information (“signal map”; histogram of fragment densities) is stored in a bigWig file, which can be visualized in genome browsers (see Section VI.). bigWig files also provide the peak metrics in the Active Motif analysis program described below.
Peak finding was performed using SICER (Zang et al., Bioinformatics 25, 1952-1958, 2009).
