DAve values for proteins and peptides selected by SVM. DAve evaluates changes in protein expression and is defined as: ((X−Y)/(X + Y))/0.5, while DCI, which describes the confidence of differential expression, is defined as: (X + Y)∗(X−Y))/2, where X and Y represent the SEQUEST-based SCORE values (or spectral count) of a given protein in two compared samples. Conventionally, signs (+/-) of DAve (and DCI) indicate if proteins are up-regulated in the first or in the second sample, respectively.
