  1. Ten algorithms (PCA, SVM, Relief, Uncertainty, Gini Index, Chi Squared, Deviation, Rule, Information Gain, and Information Gain Ratio) were used to determine the most important nucleotide attributes for the prediction of HCV subtypes 1a and 1b responders from non-responders (A) and responders from relapsers (B). Common nucleotide attributes used for genotypes 1a and 1b have been bolded. A: adenine, T: thymine, C: cytosine, G: guanine.
