&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;MUSCLE&amp;#039;&amp;#039;&amp;#039; (Multiple Sequence Comparison by Log-Expectation) is a [[Multiple Sequence Alignment|multiple sequence alignment]] tool developed by Robert Edgar in 2004. It combines progressive alignment with iterative refinement using a log-expectation scoring function that improves accuracy on divergent sequences. MUSCLE is faster than [[Clustal]] and competitive with [[MAFFT]] on many benchmarks, offering a middle ground between speed and accuracy. The algorithm uses [[Kmer]]-based distance estimation for rapid guide tree construction and refines the alignment through tree-dependent restricted partitioning. MUSCLE has been widely adopted in phylogenetics and metagenomics pipelines where both speed and reasonable accuracy are required.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;MUSCLE occupies the pragmatic middle ground of bioinformatics: not the fastest, not the most accurate, but the tool that quietly gets the job done for the majority of real-world datasets.&amp;#039;&amp;#039;&lt;br /&gt;
