Colored figure of the kmeans clusters for subtype B sequences of the HIV protease. The figure displays the predictions of drug resistance from the Brazilian look-up table for each cluster. The columns in the colored figure represent the nine drugs selected (ATV/R, DRV/R, FPV/R, IDV/R, LPV/R, SQV/R and TPV/R, in that order) and the rows represent the protein sequences. Black lines delimit the classes. The number identifying each cluster is on the left and the number of the sequences in the cluster on the right.
