Table 6 Signal ratios of SNPs are influenced by interaction of neighboring nucleotides

From: Evaluation of a microarray-hybridization based method applicable for discovery of single nucleotide polymorphisms (SNPs) in the Pseudomonas aeruginosa genome

neighboring nucleotides abundance median signal ratio sensitivityb

  1. a W – IUPAC format bases A, T showing weak interaction, S – IUPAC for G, C showing strong interaction.
  2. b determined for D th = -0.5.
  3. c SNPs in the marginal position 1 or 25 that don't have two neighboring nucleotides (see also Figure 6).
