Sequence Harmony is an entropy-based method, which accurately detects subfamily specific functional sites from a multiple sequence alignment. The algorithm implements a new formula, able to score compositional differences between subfamilies in a simple manner on an intuitive scale.

To manually align the PDB file with your input alignment, specify the starting position to match the numbering of your reference sequence to that of the PDB file. Starting position can be positive or negative.
