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.
