Figure 7.

Genome alignment accuracies for 1/9-centroid alignment compared to ordinary (Viterbi) alignment. Each point represents one combination of score parameters. A few of these are highlighted with symbols: see the key beneath the figure. Colors indicate the X-drop parameter as in Figure 4. The X-coordinate indicates the number of true positives for 1/9-centroid alignment as a fraction of the number of true positives for Viterbi alignment. Likewise for the Y-coordinate and false positives. The 1/9-centroid results alone, without comparison to Viterbi alignment, are shown in Additional file 1, Figure S9.
