Figure 1. Islander algorithm. (A and B) Population Phase: tRNA and tmRNA genes (tDNAs), tDNA fragments and integrase genes are placed on the chromosome, and each interval between a tDNA and its cognate fragments is considered a candidate island. (C) Filtering Phase: Candidates pass through several filters, including tests for an integrase gene, correct fragment/tDNA orientation and length. (D) Resolution Phase: Multiple candidates at the same tDNA are resolved, identifying tandem arrays when each island in the array has its own tDNA fragment and integrase gene.
