Data processing fastq file processed by filering out low quality reads (<Q20) and llow quality bases (<Q20) with sickle. Adaptors were removed with cutadapt 1.0.
RNA-seq data have been aligned to X. Laevis genome 6.1 using TopHat 2.0.6
ChIP-seq data have been aligned to X. Laevis genome 6.1 using BWA 0.6.2 with default options. Duplicate reads were then removed
Peaks were called using MACS2 2.0.9 with --broad options and q-value<0.01.
The list of confirmed peaks across replicates consisted of peaks with pvalue <0.01 detected in at least 2 out of 3 replicates.
MNase-seq data have been aligned to X. Laevis genome 6.1 with BWA with default options and duplicates reads were removed. Nucleosomes positions have been estimated on cell-specific merged bam files with NucHunter (-fLen = 150, -wrad 146)
MBD-seq data have been processed as ChIP-seq
Counts from RNA-seq data were extracted using HT-seq count
Differential analysis was conducted using EdgeR package
Supplementary_files_format_and_content: counts files contain counts generated using htseq-count
Supplementary_files_format_and_content: .cov files contain counts per million coverage normalized to total number of reads 1kb around TSS
Supplementary_files_format_and_content: bw files contain coverage across genome binned in 200bp windows
Supplementary_files_format_and_content: bw files contain coverage across genome binned in 50bp windows
Supplementary_files_format_and_content: bed files contains coordinate of features (i.e. for Nucleosome, putative locations of stable nucleosomes)
