Scope note A graph of the data from a position weight matrix using the letters of the residues drawn in a size that corresponds to their likelihood in the sequence. It is an alternative representation of the CONSENSUS SEQUENCE, including more information, specifically, the information about the less frequently occurring residues as well as the most frequently occurring residues.
