Data processing |
Hi-C Raw paired-end reads were controlled for quality and adapters were removed with trim_galore 0.6.2 with a quality cutoff of 20 Trimmed read pairs were processed with HICUP 0.7.3 using ^GATC,MboI as restriction enzyme and mouse mm9 as reference genome Aligned, filtered and deduplicated read pairs were converted to pairix with cooler csort 0.8.3 Resulting pairix files were then used to generate a 5kb initial contact matrix using cooler cload pairix 0.8.3 with canonical chromosome sizes of mm9 and cooler zoomify 0.8.3 was used to generate resolutions of 10kb, 20kb, 25kb, 50kb, 100kb, 200kb, 250kb, 500kb, 1Mb Each resolution was then balanced using genome-wide KR (0.05, part of HiCExplorer) and IC (part of cooler 0.8.3) using default arguments and saved into a multicooler file Similarly, juicer_tools 1.22.01 was used to generate hic files of the same resolutions and balanced with GW_KR for subsequent loop calling Loops were then called with HICCUPS 1.22.01 with arguments -m 1024 -r 5000,10000,25000 -f 0.1,0.1,0.1 -k GW_KR -p 4,2,1 -i 7,5,3 -t 0.02,1.5,1.75,2 -d 20000,20000,50000 In addition, HOMER 4.10 was used to compute compartment signals and TAD annotations by first generating a ditag directory from HICUP results using makeTagDirectory. Subsequently, compartment signals were computed with runHiCpca.pl with -res 20000 -window 200000 -genome mm9 using the RefSeq gene annotation for mm9 as markers of the active compartment. TADs were called with findTADsAndLoops.pl find with -res 5000 -balance -window 50000 -genome mm9 using known duplications for mm9 (downloaded from UCSC) as bad regions. Genome_build: UCSC mm9 Supplementary_files_format_and_content: Multicoolers contain the raw contact matrixes as well as balancing weights for KR and IC algorithms for resolutions of 5kb, 10kb, 20kb, 25kb, 50kb, 100kb, 200kb, 250kb, 500kb, 1Mb. Balancing weights for each resolution were saved in the bins table as 'weight' (KR) and 'ICE' (IC) column, respectively Supplementary_files_format_and_content: Loop annotions were converted from the HICCUPs merged_loops.bedpe file to a 2D bed file containing columns chr1, x1, x2, chr2, y1, y2, fdrBL Supplementary_files_format_and_content: TAD annotations were converted from to a domains file with columns chr, start, end, name, TADscore, strand, start, end, RGB color Supplementary_files_format_and_content: The first principal component as computed by homer was converted to bigWig with sort -k1,1 -k2,2n; bedGraphToBigWig (UCSC kent_tools/20190507-linux.x86_64) with a chromsize file containing only mm9 canonical chromosomes
