Figure 7
Histogram showing the frequency of mutations in reverse transcriptase kmeans clusters. Histograms containing the frequencies of mutations for each selected amino acid position in the reverse transcriptase for each of the six clusters in subtype B at k=6. Each histogram represents one cluster found by K-means for k=6 in the reverse transcriptase sequences. Each bar in the histogram represents a protein position and the percentage of sequences in the cluster that contain a mutation at that position.
