  1. a MaxQ measures the highest periodic signal intensity detected over the range or periods 5-20 bp. The table shows the 99th, 95th, and 50th percentile, for each combination of parameters. See text for details.
  2. b Definition of A-tracts: "AT", single nucleotides A or T; "A2T2" dinucleotides AA or TT; "AT2", dinucleotides AA, AT, or TT; "A3T3" trinucleotides AAA or TTT; "AT3", trinucleotides AAA, AAT, ATT, or TTT; etc.
  3. c The spacing range refers to the difference between parameters smax-smin. The simulations were performed for spacing range values 40, 70, 100, 150, and 200 bp. See text for details.
  4. d The 99th, 95th, and 50th percentiles, respectively, of the MaxQ values in 20,500 random sequences are shown.
