WebWhich method of multiple sequence alignment does Clustal W employ? The Clustal Omega algorithm produces a multiple sequence alignment by firstly producing pairwise alignments using the k-tuple method . Then, the sequences are clustered using the mBed method . This is followed by the k- means clustering method . WebOne such analysis method is phylogenetic placement, which establishes the phylogenetic identity of the anonymous environmental sequences in a sample by means of a given phylogenetic reference tree. However, assessing the diversity of a sample remains challenging, as traditional methods do not scale well with the increasing data volumes …
