Distribution of R b values. The histogram shows the distribution of Rb-values when BLASTing the probe sequences against four of the genomes they are designed to represent. A majority of alignments show either Rb = 0 or Rb = 1, but a large proportion of probes also have 0.7 <Rb < 1.0. By choosing the threshold between Present and Absent at 0.7 these probes are defined as Present.
