I am trying to make a cluster to analyze DNA sequences and find the less matched patterns among them (for say <25% match). Is it possible to perform cluster analysis (k-means or any other approach) for the DNA in a fasta file.
for example I want to generate a cluster graph (image) for the given data (below is the fasta sequences) and find the less similar (<25%) sequence (encircled dots)
