Comparison of our alignment results with that of MASS, OPAAS, SAMO, and Topofit for known circular permutations. Each method detected the circular permutations. Our method normally returns more equivalent residues at a lower RMSD. N indicates the number of aligned residues. An * next to the number of aligned residues indicates that a circular permutation was found. R indicates the cRMSD of the alignment. p indicates the p-value of our alignment.
