Web1. CLUSTAL简介CLUSTAL算法由 Feng 和 Doolittle等人于1987年提出，是一个渐进比对算法。渐进比对算法的基本思想是重复地利用双序列比对算法, 先由两个序列的比对开始, 逐渐添加新序列, 直到一个序列簇中的所有序列都加入为止。但是不同的添加顺序会产生不同的比对结果，因此, 确定合适的比对顺序是 ... WebNov 8, 2024 · Details. This is a function providing the ClustalW multiple alignment algorithm as an R function. It can be used for various types of sequence data (see inputSeqs argument above). Parameters that are common to all multiple sequences alignments provided by the msa package are explicitly provided by the function and named in the …
