TIBS 23 – OCTOBER 1998 COMPUTER CORNER weighting sequences on the basis of Multiple sequence alignment their divergences. In later releases of Clustal W, gap-penalty masks can guide the alignment (e.g. in cases
Gaps are scored according to their length and the number of sequences that they occur in and the method will find a multiple alignment with the best possible score. Clustal W is perhaps the most widely used program for carrying out automatic multiple alignments. It uses a simple text menu ...

多序列比对一般通过3个步骤完成:(1)两两进行双重比对。(2)生成一系统树图(dendrogram),将序列按相似性大致地分组。(3)使用系统树图作为引导,产生出最终的多序列比对结果。
实现多序列比对的方法有许多,其中最常用的方法是基于动态规划的方法,例如Clustal系列软件,如ClustalW和Clustal Omega。这些算法通过优化一个得分函数,尽量使序列在各个位置上对齐。 动态规划算法的基本原理是通过计算一个得分矩阵,并利用矩阵中的值来选择最佳的序列对齐方式。得分矩阵中的每个元素代表了相应位置上的比对得...
