Data processing Alignment: Reads that passed the Illumina quality filtering were considered for alignment. The remaining reads were aligned against the mouse genome assembly version July 2007 (NCBI37/mm9) using the BOWTIE program version 12.5 [Langmead, 2009], allowing up to two mismatches, and ignoring any read that would match more than once.
Peak calling: Peaks were called using the MACS program version [Zhang et al.] with default parameters and appropriate tag size, mm9 genome size (2654911517), sample and input read files. In cases where the read shifting model could not be build with the default mfold parameter (32), the mfold cutoff was lowered up to the point where sufficient high quality peaks could be found to build the model (100). Peaks were further filtered for p-values lower than 1e-10. This cutoff is more conservative than the default (1e-5), and worked well in removing false positive (=unique) peaks of technical replicates [data not shown].
Genome_build: mm9
Supplementary_files_format_and_content: BED files contain all uniquely aligned reads or called peaks
