WebMar 12, 2013 · For the second step, alignment of those sequences, MEGA offers two different algorithms: ClustalW and MUSCLE. For the third step, construction of a phylogenetic tree from the aligned sequences, MEGA offers many different methods. Here we illustrate the maximum likelihood method, beginning with MEGA's Models feature, … http://csbio.unc.edu/mcmillan/Comp555S16/Lecture14.html

Multiple sequence alignment using ClustalW and ClustalX

The first step to the algorithm is computing a rough distance matrix between each pair of sequences, also known as pairwise sequence alignment. The next step is a neighbor-joining method that uses midpoint rooting to create an overall guide tree. The process it uses to do this is shown in the detailed diagram for … See more Clustal is a series of widely used computer programs used in bioinformatics for multiple sequence alignment. There have been many versions of Clustal over the development of the algorithm that are listed below. The … See more There have been many variations of the Clustal software, all of which are listed below: • Clustal: The original software for multiple sequence … See more Brief summary The original program in the Clustal series of software was developed in 1988 as a way to generate multiple sequence alignments on personal computers.
