  • Peak-finding: BAM > BED using MACS



Peak-finding: BAM > BED using MACS

  • Done by Mark Teng
  • MACS: Model-based Analysis of ChIP-Seq (Zhang et al. 2008) - Given a sonication size (bandwidth) and a high-confidence fold-enrichment (mfold), MACS slides 2 bandwidth windows across the genome to find regions with tags more than mfold enriched relative to a random tag genome distribution.
  • Arguments and parameters in Excel files from Mark
