| Description |
MNase-seq of Xenopus on 601x7_12bp-linker_pUC19 1:1 histone:DNA ratio
Widom 601 7-copy array with 12-bp linkers in pUC19 cleaved with BamHI and KpnI

| Data processing |
Genome_build: pUC19-601x7_KpnI.fasta
1. We used cutadapt 2.9 with parameters "--nextseq-trim 20 -m 20 -a AGATCGGAAGAGCACACGTCTGAACTCCAGTCA -A AGATCGGAAGAGCGTCGTGTAGGGAAAGAGTGT -Z" to trim adapters off 50bp paired-end reads. 2. We used Bowtie2 2.4.2 with options "--very-sensitive-local --soft-clipped-unmapped-tlen --dovetail --no-mixed --no-discordant -q --phred33 -I 10 -X 1000" to map the trimmed reads to the reference sequence: Marseillevirus marseillevirus G648 (Genome_G648.fasta) or Widom 601 7-copy array with 12-bp linkers in pUC19 cleaved with BamHI and KpnI (pUC19-601x7_KpnI.fasta). 3. We extracted properly paired reads from the alignments with bedtools bamtobed to generate a bed file of aligned fragments (Supplementary file fragments.bed.gz). 4. We used bedtools genomecov to make a normalized count bigwig file. Normalized counts are the fraction of counts at each base pair scaled by the size of the reference sequence so that if the scaled counts were uniformly distributed there would be 1 at each position (Supplementary file normalized_counts.bigwig).
