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 is the latest addition to the Clustal family. It offers a significant increase in scalability over previous versions, allowing hundreds of thousands of sequences to be aligned in only a few hours. It will also make use of multiple processors, where present.

Oct 30, 2017 · Clustal Omega is a widely used package for carrying out multiple sequence alignment. Here, we describe some recent additions to the package and benchmark some alternative ways of making alignments.
Clustal-Omega accepts 3 types of sequence input: (i) a sequence file with un-aligned or aligned sequences, (ii) profiles (a multiple alignment in a file) of aligned sequences, (iii) a HMM. Valid combinations of the above are: (a) one file with un-aligned or aligned sequences (i); the sequences will be aligned, and the alignment will be written out.
Dec 9, 2020 · Clustal Omega [ 1] is a package for performing fast and accurate multiple sequence alignments (MSAs) of potentially large numbers of protein or DNA/RNA sequences. It is the latest version of the popular and widely used Clustal MSA package [ 2, 3 ].
Click on the Align link in the header bar to align two or more protein sequences with the Clustal Omega program. Enter either protein sequences in FASTA format or UniProt identifiers (as above) into the form field. Click the ‘Run Align’ button.
