For a vector of principal components the Q-residuals of a DNA symbolical sequence are calculated using a PCA model of the numerical DNA motif. First sequences are converted to numerical DNA sequences and then the model is applied. A matrix is returned for each number of PC with the value of the Q-residuals in each position and a label indicating if the sequence belong to a binding site or not
