Scope note: Representaciones numéricas tabulares de motivos de secuencias, que muestran su variabilidad como valores de verosimilitud para cada residuo posible en cada posición de una secuencia. Las matrices de puntuación por posiciones específicas (en inglés PSSMs) se calculan a partir de las matrices de frecuencia de posición.

Concept UI M0527629
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.
