Distance between sequences:
comparison of oligonucleotide composition

  • This tool will compute distance between input sequences and UPGMA clustering will be applied.
  • Distances are shown in a table, and a dendrogram is displaied.
  • Check carefully the results. Theirvalue for phylogenetics is limited.
Copy your sequences bellow as Fasta (Maximum length: 2 MB)

Choose method to compute distances (info)
Pearson distance for z-scores of tetranucleotides (>20000 bp sequences)   
Euclidean distance for

This is a simplified PHP script extracted from the online tool at insilico.ehu.es/oligoweb/.
