Ablation analysis of FSA on simulated unrelated protein and DNA sequences.

Ablation analysis of FSA on the unrelated sequence benchmarks of Table 4 : Comparisons of the accuracies (Acc), sensitivities (Sn) and positive predictive values (PPV) of FSA with different components enabled or disabled. From top to bottom, FSA was run in default mode, �Cfast mode, with learning disabled, with iterative refinement disabled, and with 1 set (rather than 2 sets) of indel states; these options were then repeated for maximum-sensitivity mode (�Cmaxsn). Query-specific learning helps to make FSA robust to non-homologous sequence.
