Figure 4. The sensitivities of simulated reads spanning INDELs, which is defined as the number of correct mapped reads divided by the number of simulated reads for each INDEL length.

In (A) and (B), the alignments are considered correct as they cross INDELs, while in (C) and (D), the alignments are considered correct as they are entirely or partially mapped to the correct positions. TP and FN are “true positive” and “false negative” respectively.
