Shannon Entropy-One

  Entropy-Two   Entropy-One     Entropy Readme   Entropy Options  

Purpose: This tool applies phylogenetics into Shannon entropy as a measure of variation in DNA and protein sequence alignments. ENTROPY-ONE calculates the entropy at each position in one input sequence set. It can be used as a measure of the relative variation in different positions or regions of an aligned gene or protein. For more information and details, use Entropy links above.

Use amino acid class equivalents for the calculation (ONLY for protein sequences)
Calculate the frequency of the most common
aa or nt in each position
