title: A comparison of amino acid distance measures using procrustes analysis.
abstract: Four methods to convert an amino acid similarity matrix into a metric distance matrix were compared using procrustes analysis. Procrustes analysis is a rotational fit technique, which assesses the degree of fit between two configurations after optimal matching of the two matrices under translation, rotation and scaling. The analysis shows that not all conversion methods are equivalent, but that the results of two methods are more similar than the others.
