Definición

  • Tabular numerical representations of sequence motifs displaying their variability as likelihood values for each possible residue at each position in a sequence. Position-specific scoring matrices (PSSMs) are calculated from position frequency matrices. 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. The tabular notation of the count per position of each potential residue as observed from an aligned set of sequences.
