Multiple sequence alignment (MSA) has assumed a key role in comparative structure and function analysis of biological sequences. It often leads to fundamental biological insight into sequence-structure-function relationships of nucleotide or protein sequence families. Significant advances have been achieved...
Multiple sequence alignment (MSA) of DNA, RNA, and protein sequences is one of the most essential techniques in the fields of molecular biology, computational biology, and bioinformatics. Next-generation sequencing technologies are changing the biology landscape, flooding the databases with massive ...

有人用一个二维向量代替每一个字母,字母比较变成了二维向量之间的距离;kmer(就是k-gram)之间的比较转换成向量的点乘,利用FFT变换把O(k2)降低到O(klogk),具体如何变换我也没太看明白。 Ref : Katoh K, Toh H. Recent developments in the MAFFT multiple sequence alignment program[J]. Briefings in bioinfor...
DNA规则是比对中的关键，通常将匹配视为+1分，不匹配为-3分，而每个空隙则扣罚-5分，每增加一次空隙扣罚值会进一步降低。然而，蛋白质比对中MSA的准确率较高，而在DNA序列比对中则相对较少被采用。业界的基准测试，如BAliBASE、Bioinformatics2015和RECOMB2014，为评估各种算法提供了丰富的数据集。传统的...

BIOINFORMATICS doi:10.1093/bioinformatics/btm226 Multiple alignment by aligning alignments Motivation: Multiple sequence alignment is a fundamental task in bioinformatics. Current tools typically form an initial alignment by merging subalignments, and then polish this alignment by repeated splitting and ...
