  1. *Assuming that reads mapped to mitochondrial chromosomes (M) are due to the experimental procedure and not to the non-specific binding of STAT1, the ChIP/input ratio for this background noise is 21.96%. Among chromosome 1-22 and X, the expected background noise in ChIP would be 22585024*0.2196 = 4959671, which accounts for 20.42% of total noise reads.
