WebA distance matrix is usually calculated before tree building and it requires an O(N2) memory space, where N is the number of sequences. As for time complexity, MAFFT (Katoh et al., 2002, 2005) uses an O(N3) algorithm for constructing a variant of UPGMA guide tree. MUSCLE (Edgar, 2004a,b) uses a WebJan 1, 2013 · MAFFT is a popular multiple sequence alignment (MSA) program with various options for the progressive method, the iterative refinement method and other methods. ...

Multiple alignment using fast fourier transform (MAFFT) is a program with an algorithm based on progressive alignment, and it offers various multiple alignment strategies. First, MAFFT constructs a distance matrix based on the number of shared 6-tuples. Second, it builds the guide tree based on the … See more In mathematics, computer science and especially graph theory, a distance matrix is a square matrix (two-dimensional array) containing the distances, taken pairwise, between the elements of a set. Depending upon the … See more The value of a distance matrix formalism in many applications is in how the distance matrix can manifestly encode the metric axioms and in how it lends itself to the use of linear algebra techniques. That is, if M = (xij) with 1 ≤ i, j ≤ N is a distance matrix for a metric distance, then See more The distance matrix is widely used in the bioinformatics field, and it is present in several methods, algorithms and programs. Distance matrices are used to represent See more In general, a distance matrix is a weighted adjacency matrix of some graph.
