Homopolymer modelling. The cluster centroid (1) is higher in abundance than the query sequence (2). When the query is aligned with the centroid sequence, the alignment score is maximised by the dynamic programming algorithm traversing the red path through the sequence graph defined by the query sequence and Pagan’s homopolymer heuristics.
