In the same Clustal Omega the phylogenetic relationship was observed which is distance based. Consequently there is no bootstrapping in Clustal Omega. Simple Phylogeny. There have been many variations of the Clustal software, all of which are listed below: The number of branches that are between two species indicates their relatedness, with more branches indicating that the species are distantly related. 4. Default Clustal Distance Matrix NEXUS. Please contact us via the feedback link if you have any concerns. ClustalW is a general purpose DNA or protein multiple sequence alignment program for three or more sequences. The resulting alignment and phylogenetic tree are used as a guide to produce new and more accurate weighting factors. The directions for how to do this are as follows: Align your sequences using the program Clustal Omega 12. with CLUSTAL OMEGA or MAFFT). For the alignment of two sequences please instead use our pairwise sequence alignment tools. Please read the FAQ before seeking help from our support staff.
