Clustal Omega is a new multiple sequence alignment program that uses seeded guide trees and HMM profile-profile techniques to generate alignments between three or more sequences. For the alignment of two sequences please instead use our pairwise sequence alignment tools.
Clustal Omega. Latest version of Clustal - fast and scalable (can align hundreds of thousands of sequences in hours), greater accuracy due to new HMM alignment engine.

CLUSTAL W: improving the sensitivity of progressive multiple sequence alignment through sequence weighting, position-specific gap penalties and weight matrix choice.
The ClustalW program, when used in a CLC Workbench, uses ClustalW for the alignment calculation but still retains annotations on the sequences when the alignment is displayed (see figure 2.4). One of the advantages of ClustalW is that it uses very little computer memory on rather large sequences so you can align large sequences without having a ...
The approach used in ClustalV is a modified version of the method of Feng and Doolittle (1987) who aligned the sequences in larger and larger groups according to the branching order in an initial phylogenetic tree. This approach allows a very useful combination of computational tractability and sensitivity.
CLUSTALW SEQUENCE NUMBERS: residue numbers may be added to the end of the alignment lines in clustalw format. OUTPUT ORDER is used to control the order of the sequences in the output alignments. By default, the order corresponds to the order in which the sequences were aligned (from the guide tree-dendrogram), thus automatically grouping ...
A ClustalW icon has been designed for MAC and PC systems. Changes since version 1.74 -------------------------- 1. Some work has been done to automatically select the optimal parameters depending on the set of sequences to be aligned.
The clustal family of programs is commonly used to produce multiple sequence alignments. Other options are available as well: Muscle. T-Coffee. There are 3 different ways to use the clustal programs. Web-based clustalw can be used HERE. ClustalX GUI (and also the command-line clustalw executable) is available for download HERE. exampledata.
