  1. Sub-section Variable Length refers to results of actual sequence lengths for both training and test sets (equal number of varying sequence lengths of 100, 150, and 200 from E. coli UTR chosen as negative set). Sub-sections 100, 150, and 200 refers to results where all sequences in the training and test sets have a constant length. Column Features denotes features used from the training set. T P % denotes percentage of true positives. F P 1 % and F P 2 % represent the percentages of antisense sequences and E. coli UTRs that are misclassified as riboswitches, respectively. Sensitivity denotes overall percentage of correctly classified sequences. Sig. denotes significant (less than 0.05 in the training set) features of the multinomial classifier.
