Data processing To obtain quality reads, raw reads were processed and trimmed with Trim_galore (v0.4.4) from cutadapt (DOI: 10.14806ej.17.1.200) and FASTQC analysis. A default quality score cutoff of Q20 is used. Quality trimmed reads were then mapped to "hg38+rDNA” (DOI: 10.1101/2022.11.10.514243) genome build by bwa (v0.7.12-r1039) and converted to a bam file by samtools (v1.2).
Duplicate reads were marked with biobambam2 (v2.0.87, DOI: 10.1186/175109473-9-13). Uniquely mapped and properly paired reads were then extracted with samtools (v1.2, "-F 1804 -q 1") and sorted by read name using biobambam2 (v2.0.87)
bedtools(v2.17.0, PMID: 20110278) were used to convert bam file to bedpe file as fragments. Fragments with size shorter than 2000bp were extracted and center 80bp of each fragment were used to generate bigwig track files by UCSC tools (v4) and visualized using IGV (v2.16.0).
Narrow peaks were called with MACS2 (v2.1.1.20160309, parameters "-q 0.05") and broad peaks were called by SICER (v1.1, parameters "hg38 1 200 fragmentsize 0.86 600 0.00001").
To perform statistical test between experimental groups, fragments for each reference peak were counted with intersect command from pybedtools (v0.9.1). Next, the number of raw reads mapping per peak were converted to FPKM unit (Fragments Per Kilo base per Million mapped reads), and TMM (trimmed mean of M-values) from edgeR package. Next, we used limma-voom approach to assess the significance of differential peak binding. Significant peaks were defined by log2FC < -1 or > 1 and FDR < 0.05.
